ALIEN: FALL OF THE REBEL ANGELS

Millenia ago a splinter group of Engineers broke their ancient covenant and committed the greatest sin: they stole the divine equation of creation in an attempt to usurp the Gods. The black pathogen was their greatest triumph but for their arrogance the Gods cursed those rebellious ones and turned their creation against them, spawning demons as punishment for their transgressions. 

Comic idea on some Alien mythos fanfiction. always wanted the engineers to be more space magic mixed in biomechanical black science.
