The main function of the lifeless space is to provide a dimension in which nothing decays or ages, an eternal void of emptiness. Deities may rest within it to sever their ties to either world whilst maintaining their current state. When needed they can then will themselves or other people to enter either world's reality at whim. The spontaneous transfer is equivalent to time travel. So long as the god knows its objective, it can move between either world at any time. Any reigning deity from the parallel world has the power to open or close the portal to it, but time travel is a trait that is often associated with the White Dragon.
