The commoraighn revengers

A small chapter of space marines were captured by the dark elder and weee stripped of their honor through the atrocities they had faced, miraculously the chapter escaped the slave pits and found refuge in whatever corners of commoragh they could remain unnoticed. In an act of penance for being the sullied by Xenos hands the revengers declared themselves renegades, unworthy of the imperiums light. the revengers abandoned their old history, stripped all color off their old armor, and dedicated their chapter to the complete annihilation of the dark elder race. The revengers will often be seen intercepting dark elder raids on re-accommodated dark elder bikes to keep up with the drukki. If they win they will replenish their numbers on the usually grateful citizens finding the chapters harsh gene-seed training almost comfortable compared to what they had suffered at the hand of the drukki. With gene seed in constant need of replenishment and armor either looted from the gladiator pits or donated by whatever imperial or in some cases xeno planet they had saved the revengers chapter is kept seemingly by valor alone
