Демон Базилевс ( Базиль)
Basileus is Lucifer's herald and sometimes serves as the voice of Hell itself. He generally takes on the appearance of an unearthly beautiful male of a race matching the observer's. Upon closer inspection though, one can see hellfire burning from within his eyes like two smoldering embers of hatred and fire.
Basileus is rarely encountered on Earth, since he typically serves as an ambassador or envoy between Lucifer and other demon lords or archdemons even. Rather than being promoted from within the infernal horde, Basileus was created by Lucifer himself to be the perfect emissary.
