Weird Races and Strange Places

For Halloween, some abyssal and far-realm environments

Planets At War
Abyssal layer 7716 is a solar system consisting of a black hole orbited by a small star and several dozen planets and dwarf planets. The planets are all at war with each other, literally. The planets are sentient and don't get along, and every so often one of them will try to ram one of the others into the sun or the black hole. This naturally has devestating repurcussions for both planets' inhabitants, regardless of whether it succeeds or not. New planets occasionally pop up in various ways, and so the solar system never runs out. Planets will sometimes divide by binary fission, or a new one will be spat out by the sun, sometimes one will spontaneously spin up out of space dust and debris, and sometimes a pair of twin planets will simply pop into existence out of the void; this last kind almost always immediately smash each other into dust unless one of them is sucked into the black hole or destroyed by something else first. Sun occasionally disgorges huge or even gargantuan Callers in Darkness (expanded psionics handbook), often with fire or evil related templates. The black hole even more rarely disgorges Callers in Darkness that can be up to collassal+ in size and often have multiple templates.

And the spelljamming inhabitants of the planets are also all at war with each other.

Several facilities exist in orbit around the black hole dedicated to launching interplanetary projectiles out of the black hole via the Reverse Gravity spell (from Planar Handbook)

The Forum
Abyssal layer 41315 is a massive fractally repeating Roman forum, with other types of town squares occasionally sprinkled in, serves as an assembly place for political discourse in the form of bloody violence comitted with the many weapons convemiently strewn about

The Bowels of the Underworld
(this one's actually based on a location from the computer game Afterlife)

This abyssal layer, layer 1777, is alive, specifically it appears to be the intestinal tract of some kind of enormous beast. In terms of inhabitants it boasts more human centipedes per square mile than any other location in the multiverse.


Upside-Down Spinning Mountains
This is a landscape in the Far Realm. It consists of an endless series (a square grid actually) of miles high cones, made of some otherworldly material, which face upside down, connecting to the underlaying landscape at their vertices, and rotate about their axis at a rate of about one to ten revolutions per minute. They don't face directly downwards; they are a few degrees off of vertical and precess around the vertical at a rate a little less than once per day. The landscape between he mountains is highly warped spatially. You can travel from mountain to mountain in straight lines across the grid, but the diagonal distance between them is infinite (think of trying to traverse the center of escher's Circle Limit With Butterflies; there are a finite number of butterflies around the edge, but you would have to pass an infinite number of butterflies to go through the center - the only way to get from one side to the other is to go around the edge)

EDIT:

Dictatoria
An isolated dieselpunk Ravenloft domain styled after early 20th century dystopian literature and early 20th century dictatorships. Its paranoid leader relentlessly monitors, censors, oppresses, and disappears the populace, searching for a rebel forces that don;t seem to actually exist. He is also paranoid about external enemies that don;t seem to exist. Don't seem to exist that is, except when war is declared against them, which is this domain's supernatural border closure; during times of war (which is most time) anyone trying to escape past the domain's outlying walls and gates and trenches into the surrounding mists will invariably be hit by artillery fire coming from some indeterminate external place in the distance.

Dystopialand
A modern Ravenloft domain. A representatibe democracy with frequent elections, but a very poor choice of candidates. The elections there are always tight races between the No Smiling Party, whose platform involves executing anybody (other than party elite) who does not live a life of cold discipline and self-denial, versus the Smiling Only Party, whose platform involves euthanizing anyone (other than party elite) who seems unhappy or unfriendly. The occupant of their government's highest office appears to change, but is in fact always held by the domain's darklord, who has a split personality
