Story 

You awaken in a pool in an ancient, abandoned temple for a forgotten god, at the abyss of a cliff. As you move your stiff body and regain control, you explore the ruins, finding clues to your past - how you were a great hero that was killed by a mountain god said to grant any wish if defeated. The abandoned temple shows traces of someone living there and taking care of your body. Perhaps finding them will answer the purpose of your revival. You climb up through the tower to find the exit and answers. As you break the gate seal to exit, you summon a boss fight.
