While the storyline and the progression of Valerian Night is my own madness at work, the deities we encounter throughout the work are all derived from existing mythology - that is not to say I didn't take poetic liscence here and there to twist things around some, but you get my drift. I will keep updating this as I find more sites or items of note, so keep checking back if you're interested.
