Sons of Guilliman

The Sons of Guilliman is a Codex Astartes-compliant Space Marines Chapter and a proud Successor Chapter of the Ultramarines, founded sometime during the 33rd Millennium. It gained infamy as the parent Chapter to the Chaos Space Marine warband known as Adharon’s Reavers, a Renegade group unrelated to their current actions. Hailing from the desert-ringed Death World of Praesidia, the Sons of Guilliman have a chequered past. Whispers persist that more than one of their number has fallen to the temptations of Chaos in the past, and the Chapter has a reputation for rash or wilful conduct bordering on Codex divergence.
