Ninjago Wiki
Their war was never ending.

The War of the Oni and the Dragons was the first war that began in the Realm of Oni and Dragons. The First Spinjitzu Master was born during this war. When he saw that neither side seemed intent on ending it, he decided to escape from his realm and create his own, called Ninjago.


In the beginnings, the Realm of Oni and Dragons was inhabited by Oni, demon-like creatures with the power of Destruction, and Dragons, majestic creatures with the power of Creation. Being sheer opposites, the two sides hated each other, causing chaos and war in the Realm of Oni and Dragons. One day, a child born of both worlds approached them both to end their war because he understood both sides, however, they each wanted the child as their own, so they fought harder.[1] During this time, the child befriended a dragon called Firstbourne.[2] Together they forged the Dragon Armor and sought to unite the realm. However, the child saw there would never be peace and left the Realm of Oni and Dragons in hopes of finding a new home, creating Ninjago using the four Golden Weapons of Spinjitzu.[1]
