Excommunicate Traitoris is the stamp applied to Imperial individuals[3] or groups, such as Space Marine Legions,[1] Knight Houses[4] or radical Inquisitors, that have betrayed the Imperium through heresy, mutation or any other act the Imperium deems unforgivable. Several Space Marine forces have been deemed Excommunicate, such as the Traitor Legions,[1] the Flame Falcons, the Relictors and the Soul Drinkers[2]. They are also known as Renegade Space Marines.
