Is there an air or a sea inside the rift? Or is it just endless nothingness? (and all the floating detritus you guys throw in there). The vastness of space surrounded by nothing but silence, but also the occasional cry of a beloved pet being tossed into the transformation of a lifetime.

Or maybe gently coaxed in the case of the riftborn swampie, as I'm not sure you'll be tossing them anywhere, at that size. The riftborn lain is much lighter, unless you count the weight of the existential dread of being thrown into a mysterious giant hole in space and time.
