This is just a wonderment I have, especially as to the spread (literature/movies/history).
Here's mine...
Ciann- Abdul Haq (Afgani warlord)
Widden- The Medici family (the Fraochs as a whole were imagined as Celtic Medici's)
Gog- Crocodile from One Piece. Only with an ax and a hook hand and he can't turn into sand.
Solips- Frankenstein, almost whole cloth, some alchemical theory regresses to circa 1300, but otherwise pure Frankenstein.
So where did everyone else get their mojo, or am I just less creative?
