Since the multiverse has had only OblivAeon, doing his duty as the Entropy Entity and very much not doing his duty as the Preservation Entity (effectively going postal on his job is pretty much by definition not doing it), I would imagine that the cosmic scales have swung so far toward the Entropy end of the scales that they will now boomerang back toward Preservation for a long time. Maybe there should be some sort of “end of death” storyline?
Also, just as I pointed out that The Graey was basically just the Neutral Evil plane of Hades in the D&D cosmology, that setting also has a Neutral Good plane, whose original name I forget since I always refer to it as Eden, which likewise has a “Will Save to find the will to ever leave” deal, only it’s pleasant and colorful rather than miserable and gray. So there could definitely be at least one paradise dimension in the cosmos, which is a trap that the heroes have to resist, but is only a trap in the sense of tempting you never to leave it, not in a way of making anything bad happen to you while you’re in it.
“Guise Goes To Hell” is a terrible name for a story, but “Guise Versus The Devil” is perfect.
