Serpentine War

The Serpentine War was a conflict that took place Thousands of years after the First Spinjitzu Master divided Ninjago in two and 40 years before the events of ''Ninjago: The New Timeline. ''It was fought between the five tribes of the Serpentine and the people of Ninjago, with the Anacondrai and the Elemental Masters serving as leaders of the respective sides.

The Serpentine were wreaking havoc on Ninjago, raiding places like Jamanakai Village and terrorizing those living there. The Elemental Masters formed an alliance to battle the Serpentine and protect the citizens. At Jamanakai Village, the Elemental Masters drove back the Serpentine Tribes but were forced to retreat upon the arrival of the Anacondrai. A crucial battle in the war took place at Birchwood Forest, with the Elemental Alliance fighting Arcturus and his Anacondrai, but this battle was lost as well. However, the Time Twins of the Prime Reality arrived in a base in the Swamp-lands and attacked it on January 11, 1969. The Elemental Alliance's best soldiers sacrificed their lives to ensure the base's evacuation. The Serpentine saw this as an act of honor and in 1970, a peace treaty was brokered between the humans and the Serpentine, ending the Serpentine War earlier than in the Prime Reality. The land of Ninjago was divided into two territories; the humans took the upper half and the Serpentine took the lower half. The Secret Ninja Force was created by Wu, Garmadon and the Elemental Alliance as a means of protection Ninjago from imminent danger.
