Vassago is a mighty Prince of Hell also called "Prince of Prophecy", ruling over twenty-six legions of demons. His eyes can see into other dimensions, but he is blind in this one. He can be invoked to tell events past and future and can discover hidden and lost things. Vassago is considered a good natured demon.
Stunning. I've seen your work from time to time in the feed. You always have such rich color and razor sharp edges. The human yet, inhuman quality creates just the right amount of schism to capture the eye. Wonderful.
Indeed. I don't claim to have a lot of knowledge on the subject, but I can't help but feel that most of the demonology was borrowed from other, mostly pagan, faiths. Really interesting ideas, no matter where they come from.
