The Angels Encarmine

-The Angels Encarmine (a Blood Angels Astartes Chapter) was present on Asterion centuries ago; the nature of the enemy they fought is strangely shrouded in mystery. 

 -The Chapter was stationed at Fort Orpheon, and lead by a Captain of the same name. 

 -Captain Orpheon and his angels were close allies with House Traquiel during the conflict; they gifted the family with the title of Planetary Governor, previously held by House Nimea . Melichdoche Traquiel was a particularly close ally of the Captain, having been referred to in at least one instance as "Brother Melichdoche." 

 -Much of this information was uncovered by Preacher Enoch , who has taken a particular, almost personal, interest in the Astartes Chapter. This may be related to his experience in the vision of truth , during which he experienced the events through the eyes and body of a Blood Angel.
