The Akai Amulet
The shaman caste of Ame is tasked with spiritual guidance and leadership of the tribe, as well as providing magical assistance and defense to the people of Ame as a whole. The shaman caste is composed only of spellcasters, though within that limitation it is incredibly diverse. Though most shamans within a single tribe follow a shared discipline and way of magic, it is not unlikely to find shamans of one tribe channeling arcane magic honed by years of study while those of another pursue a primal connection to nature and those of yet another devote themselves to service of a divine power.
The shaman rite of passage into adulthood is to discover a great secret, or to successfully warn of or aid in the defense against a great threat.
Shamans of Ame carry the enormous Ame spirit axe as a mark of their caste, but few are trained in its use.
