Father Glowworm

Father Glowworm is a malevolent spirit with a thirst for blood. He appeared as a great glowing eyeball the size of a wagon wheel, that had a sickly luminescent green tinge and attached to a web of pulsating veins. He was able to enter the physical world via a cave in the Earth Kingdom.

History
Father Glowworm was acquainted with many Avatars. He showed disdain for Koh the Face Stealer, believing that because of him every human thought they could come to a spirit for answers.

He had met Jianzhu at some point prior to 296 BG, and referred to him as the "Architect." They met again in that year when the earthbending master asked Father Glowworm whether Kyoshi or Yun was the Avatar. Father Glowworm was amused that the physical world was in a poor enough state for Jianzhu to ask, and told him that he would need blood.

Jianzhu affirmed that he still needed an answer, and Father Glowworm pointed to Kyoshi with a tendril, identifying her as the true Avatar. One of his tendrils then wrapped around Yun. Father Glowworm grew furious when Jianzhu assaulted him with a wall of earth to protect Kyoshi, before he and the Avatar made a swift escape from the cave.

Yun was left to Father Glowworm's mercy, his fate uncertain. The false Avatar later appeared in Qinchao acting suspiciously before killing Jianzhu.
