The Shredder’s quest takes him deep into the mountains of Japan, where he visits the temple of the Foot Mystics, an ancient sect that went dormant centuries ago. Shredder had hoped to leave their strange cult to history, but they may hold the key to defeating his powerful new enemy, the Mourner. The path is treacherous, and the Shredder will have to face more than the elements as he ascends to the secret Foot outpost.
