I wonder, could Rom's eyes be a bunch of Blacksky Eyes? Not to get too literal, but its eyes are solid black, and Rom possesses the ability to rain down--and up--a meteor storm upon the Hunter, as well as releasing arcane novae. If phantasms are the embodiment of ideas, it would make sense that Rom may have come into contact with them, metaphorically speaking.
Though, the eyes of the Pthumerians are also solid black, and I don't recall any of them possessing snowy blue arcane attacks. Still, it seems unusual that blackened eyes appear in all of these apparently "enlightened" individuals.
