Editing Cypher (section)

===Corswain===

A potential candidate based on loose circumstantial evidence (which is par for the course for Cypher). Despite being the Lion's second-in-command during the Heresy and a famous champion of the legion, Corswain is essentially unaccounted for after the Fall of Caliban. The modern Dark Angels continue to venerate him as a hero of The First, but there is no actual indication that he died at Caliban, or that he continued to lead the chapter in some capacity after the Second Founding. His last known position was kicking Fallen ass in orbit when the legion finally made it home and found everything had gone to shit.

According to [[Luther]] himself, ''his'' Lord Cypher ([[Zahariel]]) was killed by Corswain at some point during the orbital battle, though when he mentioned this, Supreme Grand Master Morderan gave him a funny look, as if it did not fit with his understanding of events, potentially meaning that either Luther was incorrect or the Dark Angels record of events was incomplete. Its worth mentioning that Morderan seemingly blew his own brains out in Luther's cell after some kind of disastrous meeting with Cypher. It also may have been the [[Watchers in the Dark]] protecting Luther instead of a suicide, but either way, the encounter with Cypher clearly rattled Morderan beyond Astartes levels of self-control.

If this is the case, it's possible that Zahariel broke the Ouroboros' influence over him and passed the title and knowledge to Corswain, with Zahariel either dying or being shipped off to the Grey Knights to become Epimethius. Also considering that he had direct knowledge of [[Tuchulcha]] and Typhus' involvement with the Warp device, Corswain is pretty well placed to become Cypher and stop Typhus and Astelan further down the timeline.

Another circumstantial piece of evidence pointing towards Corswain comes in the novel ''Unforgiven'' where Cypher tells Azrael that he would have made a good Seneschal for the Lion; a role that Corswain himself was groomed for. Unless Cypher was giving false flattery, it means he was personally familiar with the Lion at the very least; which rules out nearly all of Luther's Fallen on Caliban ''(except for a small handful)'' as they never knew their Primarch.

Corswain as Cypher is also symbolically interesting. He was one of The Lion's most loyal sons, the first outside Loyalist to reach the Solar System during the Siege of Terra, and one of the few individuals the Fallen still regard with utter dread. It's been said that Cypher holds the key to redeeming the Fallen, but that forgiveness could easily be a double-edged sword. Neither the Lion nor the Emperor were known for their forgiving nature, and Corswain was called the Hound of Caliban for a reason. In short, him being Cypher could represent final, merciless absolution a long time in the making.
