Sul-Éderos

Also known as the Breath of Spirit or the Breath of Life. The Sul-Éderos is the divine energy granted to the Duranni by Tólivar-Shûl during creation, which they in turn breathed upon Cimril Arnoth, spreading the energy and will of Tolivar-Shûl across the world and giving it shape and life.
The Sul-Éderos is the living spirit of all things. It is an omni-present energy used as a channel, and sometimes as a source, for spells, rituals, and effects for various forms of magic, particularly clerical and especially druidical magic. And, perhaps ironically, Caldanni magic (psionics).
