Barbarian invasion

The Barbarian Invasion occurred sometime before 173 ASC. Barbarians invaded the Northern Water Tribe, and defeated shortly afterward by Tonraq and his men.

History
The Barbarians invaded the North, and Tonraq was informed of this by his brother. He gathered his men and fought them off until they retreated to a sacred spiritual forest, assuming that the Water Tribe soldiers would not attack under sacred grounds. However, they assumed wrong and were promptly defeated by Tonraq and his men, which also resulted in the destruction of the forest.

Aftermath
Because of the forest's destruction, angry dark spirits invaded the Northern Water Tribe, almost resulting in its destruction. Unalaq managed to fend them off in time, using a special spirit guiding waterbending technique. Since Tonraq's actions had almost caused the North's destruction, the Chief and Tonraq's father banished Tonraq from the North. Tonraq then traveled to the south to begin a new life.
