Monastery of Spinjitzu

The Monastery of Spinjitzu was a structure built atop the tallest of the Mountains of Impossible Height. It originally served as the home of the First Spinjitzu Master, who raised his sons Garmadon and Wu within its protective walls. While training one day, Wu lost his sword and his brother Garmadon went to claim the katana outside of the monastery, however he was bitten by the young Great Devourer, whose venom slowly corrupted him. After he passed away, Wu and Garmadon inherited the Monastery, and centuries later when Garmadon went to train under Master Chen, Wu stayed at the monastery while teaching his first pupil, Morro. After Morro realized he wasn't to become the Green Ninja, he angrily left the monastery, and later died while searching for a sacred tomb.

Many years later, Garmadon's corruption would lead him to try and steal the Golden Weapons. A battle broke out between him and Wu while at the monastery, with Garmadon being banished to the Underworld. Many years later, Wu assembled a team of Ninja that comprised of Cole, Kai, Jay and Zane. The group used the monastery as their headquarters before it was burned down by the Hypnobrai tribe. To discuss their next move, the Ninja briefly met up at the monastery's ruins after Nadakhan framed them for a series of crimes. However, due to Jay's final wish, recent events were undone and the Ninja never met up at the monastery.

On the Day of the Departed, Wu returned to the monastery to commemorate his father. While there, Cole accidentally opened the Departed Realm, allowing for the resurrection of the Ninjas' old adversaries. Consequently, Morro was revived, and he went to confront Wu at the monastery. However, he sought to redeem himself and help his old Master, telling him of Yang's plan as he and Wu departed on Destiny's Bounty 2.0.
