So I received an exotic helm for my hunter from the Nightfall last night: the Achlyophage Symbiote. So I am aware of the Greek translation (I think its greek) of "Darkness Eater", but the Symbiote itself has me intrigued. The helmet itself appears common, and standard issue aside from the critter/ colony/ fungus/ alien blob growing on (or through) it. Does anyone know of any lore or back story surrounding the life form attached to the helmet?
