Tantus was the progenitor of sentience and emotion in the planes of existence.

Before humans or elves, or any such beings, Tantus weaved life into the web of weird energy that held Elethaor's creation together. This act introduced a great changeability and uncertainty to the universe - a bold rebellion against Mahacos' design of order - as an infinite number of souls now exacted their free will, albeit in a capacity far below that of the prime deities, on the elemental chaos.
