Lineage: Unknown
Founding: 21st (unknown what was done)
Skill: High/Peak Astartes
Psykers: Yes, few in number but the more skilled in the sector by far
Standoffish in the extreme but have a very close relationship with the Golden Spirit order. Bind the souls of their fallen to totems and use them to accelerate the training of the new brothers of the chapter. Based on a deathworld that they have been making more deadly over the millennia. The best doctors in the sector and possibly beyond, extremely loyal to the Imperium, the first chapter master banished an Honored daemon of Slaanesh solo.
