Monsters of chaos

The demons of chaos, alternatively translated as chaos gods or chaos monsters, are legendary entities in the Monster Girl Encyclopedia world that are sealed away in the deepest part of the sea. They were very briefly mentioned in Monster Girl Encyclopedia I, where their mystery and alleged power nevertheless made them frequent topics of interest. More recently, extra information has been revealed as the profiles for their affiliated monster girls are released.

Wandering Scholar relates the tale that, in ages past, the demons of chaos and Poseidon shared dominion over the sea. But in the age of the former Demon Lord, a war involving the demons led to them being sealed in the abyssal depths. Even today, Poseidon's power and influence doesn't stretch to the deepest parts of the sea. Although the demons of chaos were naturally male and female, they are "kin to monsters", so Wandering Scholar expects that the current Demon Lord's monster-to-monster girls sorcery will have turned them into all-girl nymphomaniac part-succubi too.

This speculation was confirmed in later profiles. The chaos monsters are the masters of the mindflayers and the creators of the shoggoths, although many of the latter fled their service in order to go out into the world and find a husband. In the shoggoth's profile we are also told that their mind-meld style sex where sensations are shared is an "incomplete imitation" of how the demons of chaos mate.
