Circle of the Abyss

Druids of the Circle of the Abyss are the protectors and seekers of the Far Realm. They work tirelessly to prevent disasters from the Far Realm from invading the material plane, or to prevent foolish travelers from getting lost in the Far Realm. Members of this circle have had an encounter with a creature or plant from the Far Realm, and have forever been changed due to it, their mind dipping in and out of maddness.

Many druids keep alien plants or small harmless creatures as objects of study. Their Druidic Groves are often influenced by images of the Far Realm, with mysterious plants growing in the area. Their groves are usually hidden by illusion, preventing wanderers who have not had an alien encounter from approaching.
