Teeleh is the ruler of the Shataiki, a species of demon bats that are about as large as dogs. He and his followers were imprisoned in the Black Forest by Elyon, the supreme creator. If anyone was to drink the water of the Black Forest, the Shataiki would be released to kill and destroy the flawless world around them. That as it is, Teeleh sought every opportunity to tempt humans into drinking his water, and finally succeeded in enticing a man named Tanis to drink from it. Teeleh and his Shataiki were released into the world, and from that point on, have been infesting humans with their disease.
