They were a faction of Eliksni.
Led in part by Mithrax's mother.
Caught in the drift... her purpose was corrupted through the desperate circumstances she survived.
Believed in complete loyalty and deference to an iron fist... hers.
Stabbed her own son as he became a man to reinforce this terminal/deadly edict.
Some of them, House of Devils... in their lust for dominance became corrupted, allowed themselves to be infected... augmented.
Everyone is trying to steal fire from the gods in Destiny.
Clovis, the Hive... the Cabal...
This is the Eliksni arc that began with Mithrax's mother during the Whirlwind eating her own people to survive.
It's ****ed up.
All trying to become Gods... all become the devil instead. Like Victor Frankenstein...
That's the Devil Splicers.
