Samurai X Cave

The Samurai X Cave is an underground base built by Nya in a desert mountain. It serves as her personal headquarters and storage for her various machines, vehicles, and gear. During the Nindroid conflict, Garmadon and Lloyd entered the cave to get Nya's car, which they used in their effort to escape the Nindroids and prevent them from capturing Lloyd.

Following the defeat of the Golden Master, Wu and Nya began rebuilding Destiny's Bounty in the cave. When the Elemental Masters returned from Chen's Island, they met up at the cave to discuss their plan of action, as the second Serpentine War was about to commence. Some time later, Morro and several of his allies entered the cave to steal some of the gear there. Ronin and Nya tried to stop them, but Ghoultar corrupted Nya's Samurai Mech, transforming it into the Mech-enstein. Some time later, Wu assembled the Ninja at the cave to tell them Ronin and Misako went missing on the Dark Island.
