What classic Deadlands arcane backgrounds am I missing?

[Trekkin]

I'm trying to compile a list of all the possible Arcane Backgrounds in classic Deadlands for character-building purposes. Thus far, I know of:

Anahuacs
Aztecs
Blessed
Blood Magicians
Hexslingers
Hucksters
Mad Scientists
Metal Mages
Voodooists

Are there any I missed, or any from its sister games (Hell on Earth, Lost Colony) that are fluffed as still functioning in the Weird West?

[Dante & Vergil]

I don't know the proper name for I think, but there was a Ki backround for Martial Artists.
