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 had 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 , although the Dark Angels themselves could can do it in under an hour, as their legion-priority overrides granted grant them ease of 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}}
