The Star Phantoms is an Astartes Chapter whose otherwise many victories remain unsung because of its own penchant for secrecy and isolationism. As part of the Sentinel Founding early in the 38th Millennium, the Chapter was founded to shore up the defenses of the Imperium in many vulnerable parts of its vast domain. Initially based in the Mausoleum-world of Haakoneth, the Chapter became fleet-based by necessity upon the destruction of the planet in 120.M40, and since that time had been grimly plying the space lanes of Segmentum Obscurus. The Chapter was counted as one of those who participated in the [[Macharian Crusade]], and was also one of the Chapters that brought back order to the worlds conquered in the crusade when the Macharian Heresy erupted after the Lord Solar's death.^c3c

The Chapter arrived in strength in the Maelstrom Zone in 912.M41, mostly due to the intervention of Legate-Inquisitor Frain and his acolytes, and pledged all of its ten Companies to the Loyalist cause^d. The Chapter's fleet, led by the [[battle barge]] ''Memento Mori'', played a pivotal part in the destruction of the infamous Ring of Steel star fort network surrounding the Badab system.^e3e

When the final attack on Badab Primaris came, the Star Phantoms were given the glory of leading the first wave of attackers. Two of its companies supported the marines of the [[Fire Hawks]] and [[Sons of Medusa]] in taking the High Guard orbital fortress, while its remaining forces, some seven companies strong, would join the heavy assault elements of the other participating Loyalist Chapters as well as Inquisitorial [[Storm Troopers]] in besieging the seat of the Tyrant's power: the Palace of Thorns itself.^f3f

Almost two hundred battle-brothers of the Chapter died in the opening assault alone, but that was only a prelude to the carnage that was to come. What followed was a deadly meat grinder of battle, as defender and attacker desperately sought to gain the upper hand in a torn cityscape that had been turned into a veritable death trap. Events soon tipped in the Loyalists' favor, but against all logic the Palace of Thorns remained unbreached, even with the participation of the Titans of Legio Crucius.^g3g

The second day of the siege fared much better, as the lightning field that had surrounded the stronghold suddenly flickered and died, an indirect result of the sabotage of countless hive reactors by the [[Space Sharks|Carcharodons]]. Although the field eventually came back up, the short period it was down was enough for the Star Phantoms assault forces, led by Captan Zhrukal Androcles, to force their way into the fortress. It was in this final assault that, through a quirk of fate, Captain Androcles and his squad encountered [[Lugft Huron]] and his honor guard in the lower catacombs of the palace. The two forces met in mutual annihilation, but while Androcles fell in the battle, he was able to apparently deal a mortal blow to the Tyrant, care of a point-blank blast from the dying Captain's combi-melta.^h3h

In recognition for their service the Star Phantoms were given dominion over the shattered remains of the Badab sector. Being fleet-based for so long, the Chapter accepted this as if it was a reward long in the coming. Taking its pick of the planets, it settled on the ice moon of Jahga, where they chose to bring down the heavily-damaged ''Momento Mori'', and use the ancient warship as a base of their new Fortress-Monastery.ⁱ³ⁱ

The Star Phantoms broadly conform to the standards laid down in the ''Codex Astartes'', but has displayed a marked preference for first strike tactics, exemplified by drop pod assaults. The Chapter also seemed to prefer long ranged bombardment using heavy weaponry over the chaos of melee, though is capable of the latter when tactically expedient to do so. For the battle-brother of the Chapter no one mode of combat holds more glory than the other; all that matters is that their enemy is disposed of^c3c.

Instead of having two [[Devastator Squad]]s per Battle Company as per Codex norm, the Star Phantoms instead have three squads of Devastators. These warriors have gained a reputation for being indiscriminate in their use of the firepower under their disposal, inflicting massive collateral damage, to the point where the Lord Solar Macharius himself is to have stated that the Chapter was "''Unsuitable for tactical close support of other Imperial Units''".^j3j

The Chapter's armory maintains an abundance of Plasma and Melta-based weaponry, and indeed it is a mark of honor among the Chapter's leaders to go into battle using a combi-plasma or combi-melta wrought by the Chapter's [[Techmarines]].^j3j

*¹'''Captain Zhrukal Androcles''' - Captain of the Star Phantoms 9th Company, he and his detachment were the ones fated to encounter the Tyrant of Badab during the climax of the siege of the Palace Thorns. In the bloody melee that followed he and his men were laid low, but not before Zhrukal himself manages to near-fatally would Lugft Huron with a blast from his combi-melta.¹
