The Corvus Umbra are a Space Marine chapter of the Raven Guard, who were founded in the 14th founding. Their gene-seed came from the Raven Guards. They are horrendously under-strength, barely fielding three companies after the many wars and treasons that have befallen their ranks. Currently led by Chapter Master Insus, the Corvus Umbra lead a thankless existence.
