Akzeriuth is a mining town that carries a big role in Tales of the Abyss. It is being plagued by miasma from underground and everyone in the city is getting sick. Malkuth's path to it is blocked so they ask the kingdom of Kimlasca to investigate. The king of Kimlasca, asks Luke Fon Fabre to be the offical Kimlasca representative. Once in the town, Luke gets tricked by Van Grants into destrpying the Sephiroth tree with the power of his hyperresonance. The entire town collapses into the Qliphoth. Tear saves the party with a force field and Van escapes but everyone else in the town died.
It was because of this incident that Kimlasca and Malkuth went to war on the Outer Lands, following the prediction of the Score. After Luke mistakenly kills so many people, he decides that he wants to change. In order to symbolize that, he cuts his hair.
