Tricksterspace
Every established deity in this crystal sphere is a rogue or trickster of some kind or another. The seasons and phases of the moon here are irregular; summer comes to the north when the god of the north steals the sun, summer comes to the south when the god of the south steals it back, and The gods of the various planets all repeatedly steal a single moon from each other under cover of darkness. There are several pornographic constellations. At least one of the sphere's planets was won by the gods in a bar bet. The powers smile on rulers who prefer spying and assassination over open war. Drinking, gambling, loud music, and prostitution play prominent roles in all societies. Animal sacrifices are offered chthonically via blood sports like dogfighting and rat baiting. Lives are wagered on sporting events like in the Aztec empire. There's a god of leather jackets, a god of switchblades, and a god of cigarrettes. Even Baator's agents in the sphere are run by Duke Ibaliclir Lord of the Underworld, an underling of Dispater in charge of organized crime.

Plutonic Space/Shared Underworld
Plutonic space is a subterranean connection between all planets. Contrary to what one might assume based on the size of a planet, there is actually no limit to how deeply one may dig other than the integrity of the tunnel or mineshaft. One may delve down hundreds or thousand times the diameter of the planet and never hit the other side of the planet. You may, however, eventually emerge on the surface of a completely different planet. This is because below their crust all planets connect to the same underworld. The planets might be imagined as wormholes connecting the underworld to the sky. The wormhole is spherical on both ends, which is why you can never reach the other side of the planet; Viewed from the sky a planet as a sphere of rock, viewed by someone who could somehow see through the rock of the underworld the planet would appear as a sphere of void. On the underworld end of the wormhole, the other side of the planet is on the other side of the sphere of void and by digging further you are traveling away from that side.
The upshot of all this is that a civilization that was sufficiently good at digging could travel to other planets without having to deal with space. It would be farther and longer than any normal voyage, and would not have the speed of a rocket, but it would be accomplishable without having to brave the vacuum of space.
Fancy's
(This one's not a world or a plane, just a location)
Fancy's is a training ground for devilish soul collectors, built to test their skill at manipulation and gaslighting. The location is disguised on the outside as an expensive upperclass restaurant. The first and easiest part of the test is that soul corruptor in training must disguise themself as a mortal, and lure a mortal dupe to the location under the pretense of a business lunch or a romantic dinner. When they arrive with their mark, the mortal is siezed and placed in a pillory in a pitch dark room for several hours and is then forced to consume rotting offal from diseased animals and robbed of all items on their person. The devil remains with them the whole time, talking to them. The final test for the trainee devil is to convince the mortal that the experience of being pilloried was actually enjoyable, or else to convince the mortal that they are a jerk or a philistine for not enjoying being pilloried in the dark, fed offal, and robbed blind. For full marks, this must be accomplished without the use of magical mind control.
The restaurant does not contain a full dining area. There is, in truth, only the one pillory and dining table. A barred window looks into the darkened dining room from the well lit area where the proctors and judges observe. This area is not directly acdessible from the dining room. To reach it, one must first go through a guardpost which leads into a small cluster of offices and barracks to which the observation room is attached.
In addion to the guardpost and its attached offices, the "dining room" also connects to a "kitchen" where sick animals are brought in and then left to die and to rot.
There are two entrences. The front entrence leads into a fake lobby/waiting room where a flunky playing the maitre'd turns away anyone who comes by and isn't part of the test. The rear entrence leads into a normal looking potemkin storeroom which in turn has a door which leads into the "kitchen".
