Nini

Nini was a resident of the Southern Water Tribe and friend of Kya's around 75 ASC. She and her entire family disappeared under mysterious circumstances during a snowstorm and were never seen again. It was strongly hinted that she froze to death.

Legend
While camping in the woods, Katara recounts how, after Nini's disappearance in a snowstorm, the men of her village formed a search party to look for her and her family. Kya, who had stayed behind in Nini's house, was alone when she heard a voice behind her saying, "It's so cold, and I can't get warm." She reportedly came face to face with Nini, who was blue as if she was frozen. When Kya brought the others back for help Nini had disappeared. Rumors persisted in the Southern Water Tribe that their house was haunted. Afterward, many villagers reported seeing smoke rising from her house's chimney, as if Nini was still trying to warm herself.

It is unknown what happened to Nini's house after the Southern Water Tribe was destroyed in the Fire Nation raids.
