Momu
this Yrashu trial was administered to any being which desired to become part of an individual tribe. The Momu activities went on "for as long as it took," since the Yrashu would not define the exact nature of the requirements for joining a given tribe. Once a being has completed the Momu, they are rewarded with a deep sense of comradie with the Yrashu trive, although they are forbidden to discuss the experience with anyone else.
