The Northern Water tribe had always been strong since the fall of Ozai. They always were willing to lend their armies to the other nations when they were in need, and were always fighting on the front lines of many of the wars. However, during the Reign of Fire Lord Rekka, the Northern Water Tribe, as well as the Southern Water Tribe, were nearly destroyed and almost all of the Waters Bender were wiped out and those who remained were either hunted or died escaping. Very few survived the Fire Nation's wrath, but those who did hid out in the Elemental Kingdom until the War was over. After Rekka was killed and Fire Lord Kouzai II took over, he helped the South and Northern Water Tribes rebuild which eventually allowed the Water Benders to repopulate and restock their numbers. The city was again attacked several years later when Ex-Prince of the Fire Nation, Sasuno'o, son of Kouzai II, attacked and nearly destroyed the city with the help of a chained Fire Spirit named Pyro. Sasuno'o bound the demon to his will and used it to attack the Water Tribe and kill their Queen, Queen Skye. However, the scar on the face of the Water Tribe was soon healed and after almost 200 years later, the Water Tribe is back and bigger than before, still sending out their forces to the aid of others when needed, and willing to help any nation in need of it. It was rebuilt in a similar fashion to the Earth Kingdom, with both metal and ice structures. Earth benders aided in the metal bending and Earth bending of homes. People also dress very differently, but the water-tribesmen still dress warmly. It's still currently rebuilding.
