T'au
| This article is about the species; for the Homeworld and Sept, see T'au (Planet). |
The T'au[26] (or Tau) are a young race of technologically-oriented beings from the Eastern Fringe and the dominant species of the T'au Empire.[1a]
T'au, the T'au home planet, was discovered in 789.M35 by the Adeptus Mechanicus Explorator Fleet ship Land's Vision. Adeptus Mechanicus records indicate that at that time, the T'au species had mastered the use of simple tools and weapons, as well as fire. Before the planet could be cleansed and colonised by the Imperium, however, a violent Warp-storm erupted around the planet. The outbreak of the wars of the Age of Apostasy shortly thereafter preempted any further Imperial follow-up and the then-minor xenos race was effectively forgotten by humanity outside a few Explorator records.[10a]
It would be another six-thousand years before the Imperium had any further contact with the T'au, when an unknown class of alien vessel was encountered by system defence ships at Devlan in the Ultima Segmentum. After failing to respond to naval challenges, the ship was attacked and destroyed. Bodies recovered from the wreckage were a close match to the records from the Land's Vision. The rapid elevation from a primitive species on a single planet to a starfaring power in only six millennia represented a new danger to Imperial interests, especially as some of the Human worlds on the fringes of Imperial territory were discovered to already have trade relations with the T'au. Almost a century later, the Damocles Crusade smashed into T'au space, bringing the two powers into war.[10c]
History
Early History
The primitive T'au were a plains-dwelling race. In their prehistory, they lived as nomadic tribes on the desert plains, hunting and gathering their food. Some of these tribes eventually expanded into other environments. The T'au of the mountains grew flaps of skin and light bones that allowed them to float over the deserts on thermal drafts. The T'au of the river valleys developed agriculture and metallurgy, forming the first true settlements. The development of settlements led to the need of trade, and wandering T'au began to negotiate and mediate between the disparate tribes, traveling up and down rivers in crude barges. The T'au that remained on the plains became strong and skillful hunters, larger and stronger than most other T'au.[10b]
Unfortunately for the T'au, the rapid sociological, biological, and technological shifts they were undergoing led to conflict. The mountain T'au and the plains T'au allied to take the farms and cities of the river valley T'au, and the merchant caravans were regularly sacked to prevent alliances from forming. The T'au of the river valleys leveraged their skill at architecture to build walls and fortresses, and quickly discovered the manufacture of black powder weaponry to defend themselves. But with the harvests disrupted, the breakdown of trade and blocked access to fresh water, disease ran rampant in the squalid conditions most T'au now lived in and as many died from sickness as battle. T'au history records this period as Mont'au, "The Terror" or "death age".[10b][8f]
T'au legends tell of the first appearance of Ethereals at the besiged city of Fio'taun after the strange lights appeared in the skies.[8c] The fortress city of Fio'taun was under assault by the warriors from the plains. Though negotiation had been attempted, the fierce plain warriors would settle for nothing less than the annihilation of Fio'taun. For five long years, the inhabitants held off the savage assaults with their thick walls and plentiful cannon. However, disease and starvation began to take their toll. As the tide of the siege turned, two mysterious T'au appeared. One made his way into the camp of the plains T'au, exuding a quiet authority that no T'au was able to resist. Soon, the leader of the plains warriors was persuaded to parley with the T'au of Fio'taun. Similarly, the other mysterious T'au made his way deep into the fortress. Within a few short hours, the gates stood wide open and the T'au stood ready to talk.[10b]
The two Ethereals spoke of the importance of peace and understanding between all T'au. They described a Greater Good that each T'au must strive for. The besiegers and the besieged quickly agreed with the Ethereals and a truce was reached. Across the land, other Ethereals emerged, each with the same quiet authority and message of harmony and cooperation. Within a few years, the Ethereals had all of T'au working together.[10b]
Expansion
First Sphere
This was a dynamic period that saw the T'au rapidly take from their homeworld T'au to the stars. Losses among the initial colonists were high, but under the protection of the Fire Caste the expansion continued undeterred. During this period the nascent T'au Empire assimilated their first alien cultures under guidance from the Ethereals, the Thraxians, the Nicassar, the Kroot and several others. The Orks were a notable exception, the savage greenskins giving the T'au their first experience of full-scale inter-species war. By the end of this period, eight major Septs had been established.[11]
Second Sphere
Fueled by the newly discovered ZFR Horizon Accelerator Engine that allowed T'au ships to make longer voyages into surrounding space, this period of T'au history is characterised by their first ventures across the Damocles Gulf. Several holdings were established on the far side, and several existent local powers were brought into the T'au fold by conquest or trade agreement. Unfortunately for the T'au, this included worlds of the Imperium of Man, a galactic power the scale of which the T'au were then-ignorant. The efforts of the Second Sphere Expansion were cut short when the Damocles Crusade quickly annihilated the T'au holdings on the far side of the gulf and proceeded to penetrate deeply into the heart of T'au territory before being fought to a stalemate at Dal'yth Sept.[8e]
Third Sphere
The wake of the Imperial withdrawl from T'au space left the Empire on the brink of collapse as the enormity of what the T'au faced was made clear. The Ethereals, realising that the Empire must quickly regain the initiative to bounce back from this loss, declared that this would be the catalyst for renewed vigour in their expansion efforts. Fleets of military conquest and colonial expansion, first led by Commander O'Shovah and then later by Commander O'Shaserra, were dispatched to reclaim territory lost to the T'au and they captured several Imperial worlds that had been stripped of their defenders to rally forces for the Battle for Macragge. Each conquest further built the T'au's strategic momentum.[10c][11]
Eventually, the Third Sphere of Expansion ground to a halt due to Imperial counterattacks in the Damocles Gulf and the formation of the Great Rift.[13]
Fourth Sphere
The Fourth Sphere of Expansion was launched shortly after the formation of the Great Rift. Utilising new anti-matter engines, the fleet was thought lost in a mass accident but in truth was cast across much of the Galaxy through a wormhole. Years after its disappearance, the Fourth Sphere was able to make contact with the T'au Empire through the wormhole, resulting in the Fifth Sphere of Expansion.[15b]
Fifth Sphere
The Fifth Sphere of Expansion was launched on the heels of the ill-fated Fourth. It is the current phase of expansion of the T'au.[13] The expedition moved into the wormhole left behind by the Fourth Sphere, now known as Startide Nexus.[15b]
Sixth Sphere
Despite the Fifth Sphere being unfinished, a Sixth Sphere is currently being planned by Ethereal Supreme Aun'va.[21b]
Society
The T'au are the most open and tolerant of the races in the Galaxy, which means that they prefer not to destroy all other races on sight and are nowhere near as xenophobic as the Imperium. They are appreciative of the ways of the humans, Eldar, and other sentient races, but hold their own values as superior above all others.[12a]
All T'au in all castes have a particular rank in their society, with each individual starting at the lowest and being eventually promoted on merit. However, the T'au attach no stigma to low rank and even the most menial T'au enjoys the respect of their peers.[12a]
Naming Conventions
T'au names are generally seen in the Imperium as long, complicated, and unwieldy, but they can be broken down into the following:
- Caste and rank within that caste.
- Sept of birth.
- Personal name (which is often determined/extended by their notable actions or achievements)
Using a T'au's full name is considered a very formal form of address, while using only their personal name is considered overly-familiar unless one is bonded to them via the Ta'lissera. Using a T'au's caste and rank to refer to them is considered a polite form of address as it acknowledges their role in the Greater Good.[12a]
Castes and Rank
The Caste System organises all T'au into five different castes and each one of them has a defined social role, be it military, trade, diplomacy, or leadership. The members of a caste are further classified by a specific rank.[12a][4c]
The castes are:
- Aun (Ethereal) - Supreme/Spiritual Leaders[4c], T'au of the Ethereal Caste are the spiritual and political leaders of the T'au, and T'au of other castes submit to their authority in all things. Should an Ethereal order a T'au of a different caste to kill themselves, they would be obeyed instantly and without question.[8f][10d]
- Por (Water) - Bureaucrats[4c], T'au of the Water Caste are the civil servants, merchants, administrators, lawyers, and diplomats of T'au society, flowing among both the other castes and other allied species and ensuring that all have what they need to optimally serve the Greater Good. They display an easy affinity for languages, and adopt many forms of communications with exceptional nuance across their careers.
- Shas (Fire) - Warriors[4c], The T'au of the Fire Caste are the warriors of T'au society and are the most massive and physically powerful of the T'au, generations of breeding having weeded out infirmity.
- Fio (Earth) - Engineers[4c], T'au of the Earth Caste have the most numerous population of all the castes, most being physically sturdy labourers who staff farms, factories and construction crews, and their brightest minds go on to be engineers and doctors.
- Kor (Air) - Spacefarers[4c], T'au of the Air Caste are sometimes known as "the invisible caste" because they spend most of their time aboard the spacecraft that make up the T'au navy. Generations of exposure to micro-gravity leaves them with hollow bones and a tolerance for high acceleration, though their frailty means they are sluggish and weak in even moderate gravity environments.
From highest to lowest, the ranks in Tau society are:[12a]
- O
- El
- Vre
- Ui
- La
- Saal[41]
Sept
T'au come from many planetary systems, or Septs, and these shape and define their methods of work. Septs are ruled by a Elemental Council, though final say goes to the Ethereal governor.[25]
Some of the most important Septs are:[12a]
- T'au - Homeworld
- T'au'n - The first Tau colony.[12b]
- Vior'la - Military centre of the T'au Empire.[12b]
- D'yanoi - Isolated for a period and considered rustic/backwards.[12b]
- Bork'an - Manufacturing hub.[12b]
- Dal'yth - Cosmopolitan.[12b]
- Fal'shia - Known for its technological innovations.[12b]
- Sa'cea - Heavily urbanised and militarised.[12b]
Personal Name
T'au personal names, unlike those of humans, usually mean things in their language, depending on the deeds in their lives. These names are apparently not assigned at birth, but descriptive of the individual as they distinguish themselves. Some examples are 'Kais' (Skillful), 'Vral' (Undercut), and 'Tsua'm' (Middle).[12a]
Example
Thus, the T'au named "Shas'O Vior'la Shovah Kais Mont'yr" (a.k.a. Commander Farsight) would be broken down as follows:
- Shas - The individual is a member of the Fire Caste...
- O - ...who is a high-ranking Commander and hero...
- Vior'la - ...who comes from the Sept of Vior'la...
...and has a personal name translated as being far-sighted (Shovah), skilled (Kais), and having seen many battles (Mont'yr, meaning "blooded").[12a]
Biology
The broad role a T'au fulfils in their society is dictated by the caste to which they are born, and each caste is physically distinct from one another, to the point of being practically separate sub-species.[10f] A T'au's appearance can easily inform a viewer of their role in T'au society.[36a]
Overview
Every T'au is humanoid in shape, with two arms,[17][36a] and two feet[Conflicting sources], and a single head with skull and brain analogous to a human's.[33a] T'au are generally shorter than humans, smaller in stature and with less muscle mass and body weight[17][Conflicting sources]. They have similar tolerances to cold, heat, and pain as the average guardsman.[17]
The caste a T'au belongs to will influence their physiology further. The Fire Caste tends to produce the strongest and largest members of the T'au, where as those of the Air Caste are taller and lighter the better for air travel. Certain mental traits are associated with each caste, though whether that is due to inborn genetics or due to social upbringing is unclear. For example those of the Water Caste are naturally able to charm others, while those of the Earth Caste tend towards skilled builders and inventors.[36a].
Head
T'au faces are flat, wide around the eyes[28a], and they possess olfactory organs containing densely-massed subdermal receptor neurons with complex of cilia.[33c] These are located inside their mouths allowing them to taste the air with their tongues and deposit air samples onto their sense organs[28a] as well as an additional olfactory slit on their faces[30d] called a Shio'he[16b]. The T'au's sense of smell is superior at short distances than a human's[28a] and is keen enough that they are able to detect the unique scent of Space Marines from a distance.[30c] They are capable of exuding scents that convey their mood and emotional state to others of their kind. [30a][30b]
Notably, T'au Ethereals possess a unique organ upon their foreheads, that can release powerful hormones; speculated but unconfirmed to play a role in controlling other castes via a pheromonal communication system or chemical 'signifiers' according to a dissection report by Magos Biologis Sharle Darvus.[33c] It is known that Ethereals exude a natural presence that inspires loyalty among the T'au, but the T'au are not inclined to research this effect.[36b]
T'au eyes are analogous in structure to that of mammals and possess a 185 degree field of view, effectively similar to humans.[33c] Their sight is thought of as slightly superior to human in some regards, able to see further into the infrared and ultraviolet spectrums. However, the lack of dilatory pupils results in a slowed reflex for focusing on objects and poorer depth perception,[28a] and though they are able to see a wider spectrum of light the direct sensitivity of their photoreceptors is poor. Magos Sharle speculates that the Tau rely on their sense of smell as well as technological aids to compensate for these vision deficits.[33c]
T'au and Humans share similar hearing ranges, with the T'au seemingly deaf to higher frequencies while capable of distinguishing sounds most humans would perceive merely as uncomfortable vibration. This has caused Imperials to consider the T'au to have lamentable taste in music.[31a]
Limbs
The T'au have three digits and a single opposable thumb on each hand. The main skeletal difference from humans is the bone structure of their lower legs, feet,[Conflicting sources] and ankles. T'au have shorter tibia and fibia equivalent bones.[17] The joints of their lower limbs are comparable to that of is various Terran Artiodactyl species. It has been speculated by by Magos Sharle that the T'au may have evolved from a Ruminant species undergone some form of accelerated evolution which have not uniformly evolve their organs.[33c] Others such as Rogue Trader Janus Draik also note the possible ancestry to Ruminant or "bovid" species.[34]
Imperial Bionics cannot naturally fit upon a T'au's physiology, and must first be customized to accommodate for their different physiologies.[36c]
Internals
T'au lungs and internal organs are generally comparable to that of humans in terms of efficiency and durability. Notably, though their heart is similar in structure to a Human heart (with atrial and ventricle structures as well as four valves) they also contain complex filter-sheathes, as well as vasculature that connects to their kidneys. The fat around their hearts contains many toxins. It is speculated that the T'au heart doubles as their liver.[33c] T'au have more than one stomach[16a] though this secondary one appears to be vestigial.[33c]
Unlike mammals, T'au bones do not possess marrow - the regulation of their immune system and platelet coagulation is dispersed beneath their skin.[33c] It has also been suggested by several Imperial observers that T'au blood is bluish-purple, explaining that the blood contains trace amounts of cobalt, rather than iron as common in humans.[5][Note 1]
Human made drugs have little effect upon a T'au, as do T'au drugs have little effect on humans. Human physicians may need to undergo specialist xenos training in order to adequately provide medical care to a T'au.[36a][38]
Skin
Broadly speaking the T'au's skin is a pale bluish-grey colour,[28a] though can vary based on the caste as well which sept world they call home. In general, it can be said that the Air Caste have the palest pigmentation, while Fire Caste tend to have the darkest. The darker the T'au’s bluish-grey skin, the closer to the sun they live - therefore those living on Vior'la have much darker skin than those from Bork'an. Also it is known that some strange quality in the green-tinged sun of the N'dras sept can leave those from that region slightly mottled.[4b][28a][36a] Their skin is leathery and tough, owing to the generally dry conditions of their homeworld,[28a][Conflicting sources] resembling the leathery texture of animal hides. In close proximity the T'au bear a bitter aroma similar to that of the spoiled milk emanating from bovines.[34]
Other
The T'au are not very good in close combat, as they find the whole concept uncivilised.[28b]
It is known that the lifespan of the T'au is short[7] typically shorter than a humans[36a], with a life expectancy of around 50 tau'cyr (40 Terran years).[22] Imperial juvenat treatments can extend this limit to upwards of 83 years, though doing so is considered unnatural[24] and any juvenat drugs will need to be customized to account for the T'au's xenos physiology.[36c] Other methods of life extension by the T'au includes Fio'O Vesa's use of T'au Microdrones - Nanobots which extend his lifespawn.[37]
Most T'au need only 1-2 decs (1.5-3 Terran hours) of sleep per every rotaa (rotaa - 15 Terran hours), so approximately 1.5 Terran hours for 15-hour T'au "day".[14b]
At least some T'au are born and raised as infants in communal Drone-operated nurseries.[27]
T'au and the Warp
The Tau have a limited understanding of the Warp. Vash’aun’an is the word for the Immaterium in Tau Lexicon.[34] Much of their understanding of the warp comes from what warp technology they are able to salvage from others.[Conflicting sources]
The T'au have no visible psykers whatsoever among their species, for their souls are so feeble they barely register in the Warp at all.[14a][15a] For a time they were largely oblivious to the malevolent forces of Chaos, who in turn took little interest in the crumbs that are T'au souls.[15a]
Because they have no Navigators, T'au ships cannot travel through the heart of the Warp like Imperium ships do. Instead, they make shallow "dives" into the Warp, a much slower form of travel. Because they have no astropaths, the T'au are reliant on messenger ships to communicate across the stars. These handicaps greatly slow the expansion of the T'au Empire.[15b][29]
The T'au do seem to have some influence on the Warp and vice-versa, as seen by the apparent Warp Entity made in the T'au's image encountered by the Fourth Sphere of Expansion.[16a]
T'au Warfare
T'au ground warfare is carried out almost exclusively by the Fire Caste, while the Air Caste is responsible for aerial and space combat, and providing transport between systems. The basic Fire Caste military unit is known as a Cadre, or Kau'ui[12a], similar in size and role to an Imperial Guard Company, and is primarily made up of T'au from the same sept.[15b]
The most commonly-fielded Cadre is a combined-arms formation (made up of multiple Teams, or La'rua), though more specialised Cadres exist such as a Battlesuit Retaliation Cadre and a Pathfinder Infiltration Cadre. Three to six Cadres will often fight together as part of a Contingent, or Tio've similar to an Imperial Guard Regiment and commanded by the most senior Cadre commander. Three to six Contingents may be grouped together into a Battle (also known as a Commune or Kavaal), though this is only a temporary formation. All Fire Caste forces in a given location, whether a planet or star system, are grouped into a Command under the leadership of a High Commander, with the four Commands (or Uash'o) (Fire, Earth, Water and Air) grouped into a Coalition (or Shan'al) under the command of the local Ethereals.[15b]
The T'au prefer to carefully plan their assaults and tend to fight only after carefully coordinating all available troops. They also prefer to fight offensively, concerned more with the destruction of the enemy than the taking and holding of ground. The T'au believe that territory is much easier to hold when all enemies are dead. Instead of trying to defend a base or city, the T'au would rather dismantle all the important technology, evacuate, and come back to defeat the occupying force at a later time when their army is sufficient for the task.
The two primary T'au tactics (known as metastrategies[16b]) are the Mont'ka (Killing Blow, metastrategy of the perfect strike[8a][16b]) and Kauyon (Patient Hunter, metastrategy of patience and ambush[8b][16b]).
Aside from these two principles, the T'au also make use of other metastrategies, including the Rinyon (Circle of Blades, metastrategy of envelopment) and the Rip'yka (Thousand Daggers, metastrategy of cumulative strikes).[16b]
The T'au have a formidable standing army but also make use of auxiliary units including the Kroot, Gue'vesa Auxiliaries and Vespid, sometimes using them as the lure in the Kauyon attack method.
T'au Warriors
The T'au Fire Caste is very much a ranged-combat oriented army. A common tactic is to engage the enemy at the maximum range of their weapons, which typically have a longer range and greater firepower than the equivalent weapons of other armies. T'au usually try to take out the strongest weapons of the enemy as well as keeping enemy troops from reaching the T'au lines, as most T'au units are weak in close combat. A more prevalent tactic amongst T'au veterans is the "Mecha-T'au" approach, which utilities the inherent mobility and speed of T'au vehicles and battlesuits to confuse and overwhelm the enemy by engaging them at all levels of the battlefield.[12c]
The T'au army is highly specialised, with each element normally having a specific task in support of the rest of the force. Fire Warrior teams make up the line troops while forward scouts known as Pathfinders scout enemy positions and provide fire support with Rail Rifles and markerlight target designators. The T'au also deploy Broadside Battlesuits and Crisis Battlesuits in supporting roles, providing specialised weapons to deal with any hot spots on the battlefield or providing heavy anti-tank fire. Stealthsuit teams operate independently of the main force, unleashing devastating fire from hidden positions.[12c]
The T'au also make extensive use of small, A.I.-controlled drones, typically equipped with guns or forcefields. Drones can be used to protect teams of Fire Warriors and battlesuits or support tanks, and can even be grouped into independent squadrons.[12c]
Technology
The Tau have a solid grasp on their own technology and have quickly developed to become one of the more technologically advanced races in the galaxy. Over the span of only a few millennia, they developed from simple hunter-gatherers using stone tools on T'au to an interstellar civilization.[15c] They have displayed high levels of proficiency of advanced technological concepts such as Plasma technology,[15e] anti-gravitic engines,[15d] robotics,[15e] and Artificial Intelligence.[15e] They are capable of great feats of stellar engineering, such as creating artificial worlds and orbital docks.[15f] Tau technology is highly dynamic, and is developing at a rapid pace compared to the other races of the galaxy.[15c]
The T'au are known to incorporate technological designs from other races to improve their own capabilities. This was displayed when they were introduced to Ion weapons by the "Demiurg", a Prospect of the Leagues of Votann and quickly produced their own models.[23] Some Earth Caste scientists have expressed an eagerness to learn the advanced technological secrets of the Aeldari. The Asuryani's wraith constructs being a particular piece of technology they see as potentially being applied to their own less-advanced battlesuits.[9]
Weaponry
The basic weapons of the Fire Caste propel particles that break down into plasma pulses as they are fired. This is commonly used in the long-range Pulse Rifle and more portable Pulse Carbine, the latter of which sports an underslung Auxiliary Grenade Launcher. A rapid-fire variation of the Pulse Carbine, known as the burst cannon, is also used on vehicles and battlesuits.[12c]
The T'au are known to use ion cannons and railguns in their ships as well as their vehicles with various guided and unguided missiles. They also arm their battlesuits with a variety of weapons, ranging from burst cannons and Missile Pods, to Fusion Blasters, Plasma Rifles and Flamers.[12c]
Space Fleet
The T'au space fleet is known as the Kor'vattra, and is crewed by T'au of the Air Caste. Since the earliest days of the First Sphere of Expansion, the Kor'vattra was given high priority by the Ethereals, and their space-faring technology advanced at a rapid pace, increasing their reach substantially in the span of a few centuries. The Kor'vattra suffered tremendous losses to the Imperial fleet during the Damocles Crusade, with their defeat at the Hydass system being particularly noteworthy. Compounding these pressures were exploring tendrils of the Tyranid hive fleets encroaching on T'au space. Following this, the Ethereals provided the very best Earth Caste scientists with whatever resources they needed to modernise and expand the Kor'vattra in a program titled the Kor'or'vesh. It is believed that the T'au's aggressive territorial expansion and the need to upgrade has placed great pressure on the Kor'vattra.[11]

Trivia
Origins
Development of the T'au originally began when Gav Thorpe sought to create a counterpart to Warhammer Fantasy's Lizardmen within the Warhammer 40,000 setting. Dubbed the "Shishell", they would include a caste system that saw the Slaan Priests of the Lizardmen changed to the Ethereals, though they were made non-psychic to differentiate them from the Eldar. The Shishell would eventually be renamed the Tau, and lose many of their lizardmen qualities, though the envisioned Caste System remained. Jes Goodwin eventually proposed a Japanese/mecha look to the T'au in order to attract new players and take advantage of the popularity of anime. According to Andy Chambers, the T'au were originally developed to be idealistic and altruistic to contrast the other factions of the setting.[20]
The Kroot were originally intended as a separate army, but were eventually folded into the T'au Empire.[20]
Tau vs T'au
When first introduced, the faction was referred to as the Tau. But beginning with 8th Edition, an apostrophe was added to the name, making it T'au, though this isn't intended to change the pronunciation.[26]
Other Notes
- Note 1: In real life, most cobalt-based compounds capable of transporting oxygen through a bloodstream would result in an amber-yellow colour when oxygenated. Copper compounds are how you get blue blood.
Conflicting sources
The Warp
- The T'au's knowledge of the warp (or lack thereof) and history with it, particularly in relation to their methods of Faster-Than-Light travel has been described differently according to various sources. See: T'au Fleet for more information.
Main article: T'au Fleet
Tau Physical Strength
- Different sources have differed on the comparisons of strength between Tau and humans.
- In Index Xenos, the T'au are stated as "having a strength equivalent to a guardsman"[28a]
- The observations of Rogue Trader Janus Draik,[34] Inquisitor Amberly Vail,[31b] Sergeant Pietr Moricani[39] and Gue'vesa Commander Jathen Korling[35] all note the T'au are weaker than humans
T'au Skin
- According to Index Xenos in White Dwarf 262 (UK), T'au skin produces "almost no moisture"[28a] while Xenology (Background Book) describes their skin as having a "high concentration of porous nodules and efficient perspiration process.[33c]
T'au Feet
- In Rogue Trader: Tau Character Guide and Imperial Armour Volume Three - The Taros Campaign, the T'au are stated to have two-toed feet[36a] with elongated cuneiform bones and tali and that they have evolved to stand and move without using their heels.[17]
- In Xenology (Background Book), on a dissection image, a T'au Ethereal is depicted with feet that have three toes.[33a]
- In War of Secrets (Novel) and Liber Xenologis they are stated as having cloven/hoofed feet.[16a][34] as do various artworks and miniatures:
