Crow's Children

"Rise up, blades of my Order! No longer shall we fight for anyone but ourselves! No longer shall we be bound by the 'honor' of our false Highlord! Rise up with me, and we shall prove our strength! Our hope lies in the Warp..."

- Knight Captain Daedelus secretly adressing the then Order of the Crow aboard the Battle Barge, "Brotherhood"

The Crows Children Chaos Warband made of traitor marines from the Penitent Knights Chapter, formed from the renegade Order of the Crow from the loyalist Chapter. Daedelus the, the Warband's Chaos Lord, fell to turn traitor against his Chapter Master, Lithandros, after constant frustrations over the Highlord's sympathy for the mortal civilian life of the Imperium. And even when Lithandros reprimanded Daedelus for disregarding orders, a strange voice whispered into the ear of the Knight Captain, telling him that he would have his day. After the mutiny of the Order of the Crow, and the company escaped into the Warp, the powers of Chaos changed them all to Chaos Space Marines, and their sole mission was to destroy their loyalist brothers.

History
Lithandros, instead of choosing to gravely punish Daedelus and his restless subordinates for disobeying orders to patrol and protect the populated planets near the Aegimius System, the Chapter's Fortress-System, decided to give him what he craved and personally led the Order of the Crow and of the Lightbound, the Terminators of the Chapter, on a Crusade around the Asteria Sub-sector. Though, when the force entered the Warp upon Lithandros’ Battle Barge, “Brotherhood”, they were set upon by a Daemonic incursion in the ship. The Order of the Crows turned upon their brothers and assisted the Daemons in killing those aboard the Brotherhood. This slaughter started in the lower decks of the Brotherhood, the daemons appearing and killing all the crewmen and stray Knights that stood in their path. Lord Scholar Pellidan Carinus, the Chief Librarian, alerted Lithandros to invasion of Chaos, directing the Lightbound to lock down choke points along the Brotherhood to either contain or slow the daemonic tide while Pellidan worked to speed them out of the Warp. It was at that point that the Crows turned, opening fire and throwing grenades at the backs of the Paladins of the Lightbound. However, the Order of the Lightbound raged and held off their traitor brothers and daemons for hours before the Battle Barge exited the Warp, the entire Order of the Lightbound slain during the betrayal, the Paladin Captain Fortareis cut down saving Lithandros from a fatal blow. Their mutiny only partly successful, what remained of the Order of the Crow fled into the Warp with their new daemonic allies, to rebuild and become the Crow’s Children Warband.
