A boarding school located near NINJAGO City, initially designed to teach bad boys how to be future evil masterminds. Multiple passageways and secret panels seem to reflect the convoluted style of thinking that villains must have. Young Lloyd Garmadon was a student here but he ran away. When he became good, the news of this led to the school renaming itself Darkly’s Boarding School for Great Children. The old teachers quit, as they were committed to evil. Later, the students of the school revolted against the new “good” teachers and tried to lure the ninja into a trap. After the ninja prevailed, peace was restored to the institution.
