[[Image:InvincibleReason.jpg|thumb|right|220px|The Invincible Reason{{Fn|8}}]]The '''''Invincible Reason''''' was a [[Gloriana Class Battleship]] which served as the flagship of the [[Dark Angels]] [[Space Marine Legion|Legion]] during the [[Great Crusade]] and [[Horus Heresy]]. {{Fn|1}}

The personal ship of [[Primarch]] [[Lion El'Jonson]], the ''Invincible Reason'' led was the Dark Angels effort in the [[Battle first ''Gloriana''-class vessel to be constructed. As a result, it had a level of Diamat]] detail and craftsmanship not seen in subsequent vessels.{{Fn|4}} During the [[Thramas Great Crusade]]. Following the Thramas ambush against the [[Night Lords]], Castellan [[Konrad CurzeDuriel (Dark Angels)|Duriel]] became stranded on board the ''Invincible Reason'' for a time. However the Night Haunter found ample hiding places on the immense vessel, was installed into its command chair and terrorized the bowels was in command of the ship despite repeated Dark Angels search parties. He eventually left the vessel when the Lion led the Dark Angels fleet to [[MacraggeLion El'Jonson|The Lion]]was not aboard.{{Fn|1}}{{Fn|27a}}

The ''Invincible Reason'' was a colossal vessel even by the standards of other ''Gloriana'' class Battleships, stretching out a total of twenty-eight kilometres from bow to stern, with a grand processional positioned under its dorsoventral spine that ran the entire length of the ship. Along this were inbuilt strongpoints that would serve as checkpoints for thousands of her million-strong crew of men and women to transit through every hour while attending to their duties. When they did, their transit authorisations, ident wafers, order papers and subdermal signum pips were scanned and verified in a largely automated process. As high-grade [[servitors]] encased in polished metal, outfitted with subtle First Legion devices bearing the manufactory stamp of the [[Terra|Ural]] forges, issued ­dozens of authorisations every second.{{Fn|7b}} A system of [[Grav-Vehicle|grav-trains]] also ran throughout the ship, and could transport anything from super-heavy equipment to crew personnel to various points within the vessel. While the hangers of the ''Invincible Reason'' could accommodate landmass sized squadrons of super-heavy craft, such as [[Monarch]] heavy landers.{{Fn|7c}} The internal layout of the ''Invincible Reason'' is a puzzle designed to baffle any who have not earned the privilege of being there, and it is said that there is no such thing as an easy route aboard her. Journeys across the ship would take her [[Chapter Serf|mortal serfs]] the better part of a day to complete, although the Dark Angels themselves can do it in under an hour, as their legion-priority overrides grant them access to the vessel’s mag-lifts and grav-rails.{{Fn|7f}}  In contrast to most expeditionary vessels, the ''Invincible Reason'', like other First Legion warships, lacked the typical hordes of crimson robed [[tech-priests]] beetling about its interiors. As the Dark Angel’s [[forge-wright]]s and [[Techmarines]] were capable of tending to all but the most arcane and intemperate of its technologies themselves, and did so.{{Fn|7a}} For weaponry the ''Invincible Reason'' possessed [[lance]]s{{Fn|7e}} and many hundreds of [[Macroweapon|Macro-ordnance batteries]].{{Fn|7f}} ==History=====Horus Heresy===The personal ship of [[Primarch]] [[Lion El'Jonson]]{{Fn|1}}, the ''Invincible Reason'' led the Dark Angels' effort in the [[Rangdan Xenocides]], the [[Battle of Diamat]], and the [[Thramas Crusade]]. Following the Thramas ambush against the [[Night Lords]], [[Konrad Curze]] became stranded on board the ''Invincible Reason'' for a time. However, the Night Haunter found ample hiding places on the immense vessel, and terrorized the bowels of the ship despite repeated Dark Angels search parties. He eventually left the vessel when the Lion led the Dark Angels' fleet to [[Macragge]].{{Fn|2}} Upon the defeat of Curze on Macragge by the Lion, the Night Lords Primarch was again chained within the ''Invincible Reason''. Following the abolition of [[Imperium Secundus]] and the journey by [[Roboute Guilliman]], and [[Sanguinius]] through the [[Ruinstorm]] to try and reach [[Terra]], the vessel was apart part of the combined loyalist fleet. However , upon the arrival at [[Davin]], Sanguinius boarded the ''Invincible Reason'' and took the captive Curze with him for his own pilgrimage on the world, dispatching several Dark Angels guards through non-lethal force in the process. In the subsequent [[Second Battle of Davin]] the ''Invincible Reason'' engaged in a vicious duel with the [[Daemonship]] ''[[Veritas Ferrum]]''.{{Fn|3}} Later during The Lion's [[Exterminatus]] of [[Barbarus]] the ''Invincible Reason'' was attacked by the [[Emperor's Children]] [[Heavy Cruiser]] ''[[Sybarite (Heavy Crusier)|Sybarite]]'', which was now possessed entirely by a [[Daemon]]. The ''Invincible Reason'' was heavily damaged in the battle after the ''Sybarite'' rammed it. The vessel sought repairs on the [[Forge World]] of [[Thagria]].{{Fn|6}} ===Post-Heresy===The ''Invincible Reason'' survived the Heresy and today remains the flagship of the Dark Angels fleet. During the [[Siege of the Fenris System]], [[Azrael]] led his operation from the vessel.{{Fn|5}} ==Notable Locations==*[[The Dreadwing Sacristy]]{{Fn|7d}} ==See also==*[[Known Vessels of the Dark Angels]]
