Editing Corswain (section)

===The Siege of Terra===

Corswain wouldn't properly resurface again until The [[Siege of Terra]], when suddenly he, and part of the Dark Angels legion, came screeching into the Sol system and hailed the Loyalist fleet that had been forced to retreat to Saturn, saying that they were here to reinforce Terra. The loyalists were very happy about the reinforcements and the armada ordered Corswain to fall in with them and to be ready to help evacuate the Emperor if the time called for it, however Corswain didn't think that hiding in Saturn's rings was manly enough and so came up with his own plan. Going to the [[Phalanx]] Corswain told the fleet that he planned to land on Terra and relight the [[Astronomicon]] so that the other legions and fleets could make it back to Terra. This plan was met with a resounding "are you mental?" by the other commanders, but Corswain pointed out that he had arrived at Terra by chance and that unless they relit the Astronomicon no other reinforcements would be likely to arrive in time. Realising he had a point, the Armada agreed to his plan and sent the [[Gloriana-class Battleship|Imperator Somnium]], one of the Emperors flagship from the [[Great Crusade]], to aid him as it had the technology to hide the Dark Angels and the fire power to punch a hole through part of the traitor fleet. The Imperator Somnium was cleared of all personnel except for the servitors and 3 [[Custodes]] and it, along with the Dark Angels ships, ripped a hole in the traitors line and allowed the Dark Angels to enact [[Steel Rain|"Teh Shteel Rhein Prohtekwal"]] on the Hollow mountain while the Imperator Somnium fought to its death above them.

The Hollow mountain was defended by the [[Emperor's Children]], who were not expecting the First Legion to suddenly fall out of the sky on their heads. They proceeded to get fucked up by the Dark Angels and not even [[Vassukella]], Daemon Prince of the Ruinstorm, was able to stop them. After securing the Hollow Mountain, Corswain sent a message to [[Rogal Dorn]] that he had arrived, secured the Hollow Mountain and was currently figuring out a way to relight the Astronomicon. A Dark Angel under his command called Vassago suggested using the old lore of [[Caliban]] to do so, which seeing no better way Corswain agreed to. What Corswain didn't know was that Vassago was a member of, you guessed it, [[Fallen Angels|the Fallen]] that had joined Corswain's forces when he had returned to Caliban to reinforce his part of the legion. Vassago had orders from [[Luther]] to make sure Caliban came out on top of the Heresy, and was initially instructed with killing Corswain but had decided against it after seeing the traitor forces and realised that they would most likely attack Caliban if they won. Vassago was then surrounded by other members of the Fallen and bitched at for not killing Corswain, and then confronted by a hooded figure (who's probably Cypher) and attacked.

Regardless of their success at relighting the beacon and calling Ultramar for aid, Corswain and his knights were ordered by [[Sanguinius]] to stay frosty and hold the Astronomicon as long as possible against relentless traitor attacks (presumably comprised of Typhus and every other Death Guard remaining in the Siege seeking vengeance against the 1st for the [[Barbarus]] Bootyblasting) rather than join up with the other legions for the last stand at the Eternity Gate.

Corswain would survive the Heresy and go on to fight against the Fallen at [[Caliban]], the details of what happened and if he even survived that battle (he probably did, because he's pretty tough) are currently unknown.
