Fall of the Fifth Nation

The Fall of the Fifth Nation was a battle in the South Pole between the pirates of the Fifth Nation and the companions of Jianzhu and the supposed Avatar Yun. Tagaka, the leader of the Fifth Nation, originally planned to ambush Yun and his allies, but her plans were foiled by the presence of Kyoshi, a member of Yun's entourage who, unbeknowest to anyone else, was the true Avatar. The Fifth Nation would have many of its members killed or captured in the battle, Tagaka among them, and nearly all of its ships destroyed, shattering its power.
