Anyone foolish enough to travel to the Dark Realm, and fortunate enough to survive the journey, will always remember their first sight of the Mountain of Madness. Some say the place got its name because you would have to be crazy to go there. The dominant peak is a volcano that spews blue lava and is home to Mud Monsters and vicious stone creatures called Craglings. Garmadon and Wu travel here because a natural portal back to the NINJAGO world exists at the peak.
