The First Spinjitzu Master's origins are unknown, but he created the world of Ninjago using the Four Golden Weapons of Spinjitzu. The new land was at peace for a while, but darkness eventually manifested to counterbalance the light of Ninjago. From the darkness came an evil creature called "The Overlord", who challenged the First Spinjitzu Master to battle for the fate of the world. The First Spinjitzu Master passed away when Wu and Garmadon were young men, charging his sons with the duty to guard the Four Golden Weapons from those who would misuse their power.
