#### Demons

Demons are commonly observed escaping from various portals into [Mundus](/wiki/bicolline/other/mundus/), sometimes by accident and sometimes through pact magic, the occult art that uses human skulls in exchange for power. One of the most famous of these beings is **[Tenamuach](/wiki/bicolline/supernatural/tenamuach/)**, known to some as the Great Devourer. It was difficult for me to find more information on these beings and their nature. Followers of the religion [Tératos](/wiki/bicolline/religions/teratos/) and those that follow the occult art of skull magic might have additional information or theories. 

I am not sure about the relationship between demons and other planer entities.
