Changes

The orbiting [[Chaos]] fleet soon became alerted to Acheran's attack and as it began moving to aid [[Nemendghast]], the crew of the Captain's [[Strike Cruiser]] ''[[Carpatia]]'' warned Acheran of the fleet. The Captain then immediately led the remnants of his forces in a final attack that destroyed the [[Daemon]] factories, but by then they were swarmed by the [[Black Legion]]. Acheran knew they could not break free from the [[Traitor]]s and instead ordered the [[Vanguard Librarian]] [[Maltis]], to escape and bring word of what had happened to [[Chapter Master]] [[Calgar]]. Maltis successfully returned to the ''Carpatia'', which then escaped to [[Vigilus]].{{Fn|2}}

Acheran would survive his battle on [[Nemendghast]] though, and later took part in the [[Fourth Tyrannic War]]. During the affair surrounding [[Project Aurora]], the [[Space Marine Captain|Captain]] reincorporated [[Demetrian Titus]] as a [[Space Marine Lieutenant|Lieutenant]] into the [[2nd Company (Ultramarines)|2nd Company]], while it defended the [[Recidious System]] from [[Tyranids]]. However, Acheran still had some suspicions of Titus, due to his history as a [[Deathwatch Blackshield]] and detainment by the [[Inquisition]].{{Fn|3a}} The [[Thousand Sons]] later invaded the [[System]] as well and the 2nd fought the [[Traitor Legion]], under their [[Chapter Master]] [[Marneus Calgar]]'s command, on the Recidious [[moon]], [[Demerium]]. The [[Ultramarines]] emerged vicarious over the Thousand Sons and Acheran later congratulated Titus for his efforts in defending the the System after the battle.{{Fn|3b}}
