A divine entity or powerful being who holds one of The Twenty Domains' artifacts following The Beleaguered Return.
Marakkus possesses the Crown of the Avatar, the artifact of the Nature domain (Preservation × Mind Sphere).
The title "Avatar" and the Nature domain suggest Marakkus may represent or embody the natural world in some form. The combination of Preservation and Mind points to consciousness within nature, perhaps representing the living intelligence of the natural order.
Little else is known about Marakkus's nature, allegiances, or role in the divine conflicts of Tarras.
