Spirit World firefly


 * This article is about the creature in the Spirit World. For the creature in the Northern Air Temple, see firefly. For the creature in the swamp, see glow fly.

A Spirit World firefly is an unusual Spirit World creature made up entirely of glowing light. It has been said that following the creature's light can lead a person to what they seek.

History
When Aang visited the Spirit World in an effort to get aid from Tui and La, he disturbed an odd spirit's meditation. A firefly passed by, and he suggested Aang follow it as it may lead him to what he was looking for. It led Aang to Avatar Roku, who told him about the spirit Koh.

When Aang was in a coma after Azula's lightning attack, he was tasked with catching multiple Spirit World fireflies and putting them in a lantern. Once he completed the task, Roku's animal guide Fang appeared to guide him to Roku.
