[@Mae] Rex himself never had a realm of his own creation, however, he did have a place he called home. Three guesses? It was the Void. A vastness of empty space and darkness, and breeding grounds for unspeakable horrors. It was believed that some primordial gods, including Rex himself, first emerged from the its watery depth. While out of his body (or any mortal bodies for that matter), he constantly feels its pull. Back in his better days, Rex was known to succumb to the pull every now and then, crawling back under the blanket of darkness for a nap every few centuries before emerging again. It was fitting that the gods who killed him chose it as his burial site, as well as many others. The realm itself does not fall to the manipulation from any other gods, including Rex himself, and was considered hostile to any form of life and even the smaller hint of power. Rex is just better adapted to its darkness than most.
