Buddha - (not a real deity as such) His philosophies and ideals of enlightenment and peace are flawless.
Bacchus/ Dionysus- The Roman/Greek god of wine... need I say more.
Bast - Egyptian cat goddess (thanks to her, all cats were sacred in Ancient Egypt).
.........
Satan - I know it's obvious, but (whatever you want to call him) it's the devil himself:
"Keeping Christians on their toes since the dawn of time."
-
Nurgle (the fictional Chaos god from Warhammer and Warhammer 40'000) - God of decay, bringer of plagues and pestilence. There is an unavoidable philosophy of decay that I think is cool... all things must rot.
There's probably more, but that's enough for now methinks. Anyone here a fan of
Hecate (Greek goddess of the Underworld and witchcraft)?...
