Located on the warrior training grounds, the Water Tribe armory is where Water Tribe weapons are stored and kept in pristine condition. The armory doubles as a war planning room where orders are given to the warriors.Some Fire Nation uniforms are also kept there, captured about eighty five years prior, possibly during a previous expedition against the Northern Water Tribe.
Note: If you are a warrior of the water tribe, regardless if you come from the Northern or Southern tribe, you can make requests for a personal weapon like a sword or a spear. However, unrealistic requests (e.g. A metal shield which can turn into a spear) will be denied.
