"Diegetics", by L. Ron Gygax
Most historians agree that shamanic practices were introduced by the Horde invading Azeroth from Draenor via the Dark Portal.Druids weren't shamans. Shaman is a very specific thing, and off the top of my head I can't think of a European shamanic tradition (but i am not well versed in eastern Europe history and tradition, so i could be wrong). Druids were priests of the celtic gods.
