Oni Fortress

This Oni stronghold was inhabited by the Oni millenniums ago. The Ninja found a clue to the Dragon Armor, a map showing its location. It's only appearances was in Welcome to Hollywood, Operation Anacondrai, and The End? The fortress was destroyed by the Mystake, and by far the only stronghold not owned by the Dragon Hunters since it is so deep in the Oni Land.
