Well, my form of Shamanism is sorta.... a blend of other cultures. If you have read VAT's page, then you'll see the specifics. It's not traditional Shamanism in any sense, but rather, a mixture of Plains Nations, Greco/Roman, Norse, and Inuit mythology. 

(Also Uskri's intro post in his CS will shed some light on it, as well.)

A little bit of Japanese Youkai in there as well.
