First Defense of Aevis

The First Defense of Aevis is the earliest recorded engagement of the Ironclad Templars Space Marine Chapter when they defended their home world of Aevis against a large Drukhari raiding force. Tragically, the history of the chapter was lost during the First Defense of Aevis, where part of the chapter's vaults was burned down by Drukhari Kabalite Warriors. The number of crusades the chapter have been on is unknown as the records where lost in the vault fire.

Background
Not long after the chapters founding on the planet of Aevis, a large Drukhari invasion force was heading for the chapters home world. It'd be a complete disaster massacre for the Ironclad Templars and some Imperial Fists that were still setting up on the new planet of theirs. But someone else wanted the planet. By the time the Ironclad Templars realized what was going on it was too late. High Marshall Cylux (first name unknown) quickly set up a defence to stop the invasion, but it wouldn't be enough. The Invasion force of the Drukhari was too strong, the chapter took massive amounts of loses even with their small number of Astarte's to begin with. But through honour and devotion the dwindling defenders held out longer than expected, but the Drukhari just kept reinforcing before the High Marshall could reorganize. The remaining defenders were then forced into the fortress vaults, where Cylux gave the order for some of the remaining Astarte's to escape in order for a chance for the chapter to survive. After that, all that was left was High Marshall Cylux and a handful of Sword Brethren who thought and held against the attackers for hours until they were surrounded and killed.
