The Oblivion Trials

Inside each fighter are three types of magic. If a fighter acquires magical weapons, they can best those more powerful than themselves. Provided the weapons don't eat their soul. Devol and his two friends have been provided a choice. To take a test and graduate... Or die. Each of their mentors believe they are ready. However, most who take the test never finish it alive. Can Devol, Asla and Jazai pass this test? Or will they lose one of their friends? Further, what is Koli doing in the test, and will he help them or continue his effort to kill them?
