Outcast Dead - Freedom: With Kai Zulane in tow, the Outcast Dead proceeded to escape from The Vault. Atharva naturally took the role of the band's leader due to his knowledge of the layout of The Vault and the true reason why Zulane had to survive at all costs. During their escape from The Vault, each Astartes' personality and characteristics became apparent to his fellow survivors. Atharva became the natural leader of the group, with his calm and methodical approach to all problems while Tagore managed to keep his obvious bloodlust and violent nature barely suppressed though even he recognised Atharva as the best candidate for command. Asubha and Subha, despite being identical twins, were nothing alike. Subha, dubbed the "butcher," possessed a savage, violent streak; while Asubha was called the "assassin" due to his ability to control his rage and take a tactical approach to problems that was rare in a World Eater. Argentus Kiron and Urhu Gythua formed a close friendship; Gythua earned the nickname "Goliath" due to his size and ability to soak up fire without taking much damage, while Kiron continued the pursuit of perfection and beauty that defined so many of his fellow Emperor's Children. Severian became the loner of the pack, nicknamed the "Wolf" and choosing to fight on his own rather than alongside his brothers.Shortly after rescuing Zulane, the Outcast Dead came across their first major set of defences, a 2-metre-thick door surrounded by Gun Servitors and ceiling gun emplacements. Upon recognising the Outcast Dead as a threat, all the weapons open fired without warning. Luckily enough, the escapees managed to place themselves flat against the corridor's cell doors which allowed them to take cover from the barrage of automated fire. With a kine-shield protecting him from the laser and solid slug rounds, Atharva slowly made his way forward to the door in front of him. Channelling his considerable psychic power into the decapitated head of Custodian Udar, Atharva managed to deactivate the weapons and open the door by using Udar's voice and retinal print to fool the prison's security scanners.During their escape from The Vault, the Outcast Dead came across many more defences, from further automated gun emplacements to squads of Imperial Army Storm Troopers. Throughout their escape attempt, each Astartes of the Outcast Dead made use of their particular talents to defeat the opposition. During ambushes set up by the gaolers, Severian struck from the shadows before the trap could be sprung, while Tagore and Asubha pushed back each new assault with ferocious power and savage blood-lust while Subha protected the weak form of Kai Zulane with his own massive bulk. When gunfire filled the corridors, Kiron took down his foes with well-placed headshots from his Plasma Carbine. When the escapees were pinned down by substantial fire, Gythua waded through shots, barricades and men alike, seemingly unharmed no matter how many hits he had to bear. None of The Vault's defences could stand against the group, for Atharva deactivated and opened all doors by psychically activating Udar's head when necessary and making liberal use of his Custodes identification ring.Fighting their way through numerous guard details, Gun Servitors and fixed defensive emplacements in this manner, the Outcast Dead and Kai Zulane finally made it to the entrance of the Vault, and emerged into the crisp mountain air of Terra for the first time in many months.
