The Realm Ethereal has existed since the inception of time. It reaches throughout all the known multiverses, weaving its way through multiple dimensions, planes, realities and worlds. The realm is inhabited primarily by the Ethereals. But there are also Ethereal Guardsmen, a multitude of Ethereal Creatures and those half-human/half-Ethereals known as Metaterrans. They are all interconnected as each plane interacts and influences one another.
