In The Heart of the World
The Shaman’s creed is that the divine is everywhere. Shamans commune with the spirit world, and through the intercession of the spirits, can cast divine spells. Shamans are respected throughout the empire, though they are most commonly found outside of major cities, that they might be closer to the natural world and the source of their power. Generally, shamanic magic is seen as an extension of the natural order of the world.
In game terms, Shamans are something of a blend of druids and clerics, with a little monk thrown in.
