The Battle in the Spirit Wilds was a confrontation between firbending humans and spirits that occurred around 9,830 BSC.

History
After hearing of Wan's survival in the spirit wilds several citizens of the fire lion tururtle city left the protection of their gaurdian in favor of occupying their own land. After several years the firebenders had burned down much of the forest  held sacred to the spirits and established a small village. In that  time they had several conflicts with the spirits, costing them many casualties.

Battle
Shortly after Wan and Raava arrived at the firebenders' settlement, and army of spirits lead by an aye-aye spirit approached the humans. Jaya ordered his men to charged toward their enemies in hopes of wiping them out. The aye-aye spirit demanded the humans leave the forest, while Wan proposed that both sides work out a compromise. When neither side would agree, Vaatu arrived on the scene causing the spirits to become infused with his darkness. Both sides charged toward one another while Wan and Raava attempted to hold them off. The two soon fused allowing Wan to display his mastery of the four elements, stunning the humans and spirits  for a brief moment. However when Wan passed out and was taken to safety by Raava the two sides quickly resumed their violent conflict.

Aftermath
The battle ended in a victory for the dark spirits with all human combatants being annihilated. As a result of the massacre Vaatu's power was increased considerably while Raava's power was diminished.
