And for what it is worth, Dr. Facilier is largely based on Baron Samedi who is one of the Loa in Voodoo (the top hat gives him away) responsible for the dead.
Ooh, good point! Although I also think that we’re going with Hades. Doc Facilier’s connection to Charon and the Furies would be tenuous at best. Also, Facilier is more of a trickster figure (much like Rumplestiltskin, with the same sort of wheeling and dealing function) rather than a God-like figure. The casting news talks about a “Devil” character — I think Facilier is at the imp level of the evil totem pole. ^-^
