Astarte

Astarte is the collected thoughts of all demonfolk.

They are ghosts sailing along the sea of thoughts, which makes it hard for them to maintain control.

As Astarte is a collection of thoughts, it is very knowledgeable/wise.

Since Astarte is a collection of thoughts it does not care what happens throughout the world. But it will do it best to try and protect those that the demonfolk hold dear.
