Long ago, the eight tribes of the Softoy Valley put aside their differences and united in peace to erect a great monument to test the mettle of their young men and women. Only by defeating the challenges and guardian of the monolith could a child demonstrate their strength and wisdom to complete their coming of age in the community. All of the tests can be defeated by mind or might in recognition that each member of the tribe has unique skills that can benefit everyone.
Although the tribes are long since gone, the monolith remains for adventurers to test their skills.
