Bruja
From Warhammer 40k - Lexicanum
Bruja was a Chaos worshipping priest from Davin and a member of the Serpent Lodge. During the Horus Heresy he was tasked by Horus with corrupting the Signus Cluster in advance of the arrival of the Blood Angels. Bruja arrived in the system as an Imperial envoy, before bursting apart and serving as a vessel for the Keeper of Secrets Kyriss the Perverse to enter the Materium. Bruja and his men also brought the Ragefire to the Signus Cluster before his death.[1]
