Demon

Demons are monsters that come from the After. They can take many shapes, such as blue two-headed monsters, red creatures with bat wings, and more. Much about them is unknown, but they at least sometimes eat meat, and they are friendly with the natives and descended of Tylaren, but hostile with invaders. They are also confirmed to have individual names, and are also shown to have other signs of being sentient and, indeed, civilized.

Language
Demons speak over 7,000 languages, and make changes to their languages frequently based on their individual preferences. It is implied that certain non-demons, such as Tendai, speak some of the demonic languages.

List of demons
So far, the only demons to be seen are Spedri (the demon who killed Tau) and Blutkae (a demon who attacked Kgosi early on in the comic). More demons are likely to appear, however.
