The Darkness, The Void and The Mists, are the same place. The place that surrounds the planes. It is the fog, the sea and the place were the paths between the worlds exist and travel can happen. The Mists hold the worlds of Godai, Bavan, Delmore, Aeladin and many others, countless others, who knows how many. The scholars of Bavan have found 100's if not thousands of worlds teeming with life and potential trade. Along the phyiscal worlds like Bavan, the elemental and outer planes can be reach within the mists, hard to travel to, Many of the paths are guarded by entities of demigod like abilities. Some have gates built to stop creatures entering or leaving the plane. So if you sent to the Nine Hells after death its the same nine hells if you from Delmore or Bavan, And the gods that are worshipped in one World are the same as in an other, maybe under a different name or a different face but many gods are worshipped in all the worlds.
