Ungula

Somewhere in the void is a star that by all rights should have collapsed in on itself and gone supernova a long time ago. It won't, of course.

Swirling around that star is a collection of planets, moons, asteroids, and other bodies that by all rights should have spun off into the abyss, fallen into the sun, or crashed into each other a long time ago. They won't, of course.

Inhabiting that collection of planets, moons, asteroids, and other bodies is a staggering array of living creatures, walking, swimming, and flying on any number of legs you care to name, all of which, for a number of reasons, by all rights should have perished a long time ago.

They won't, of course. Harmony willing.

Let us now enumerate these bodies that comprise the Ungula system.

Every star system must have its star, and Ungula's star is named Celestia. It is named this after the reason it has not exploded.

Nearest to Celestia is a red planet named Tartarus. Sweltering and inhospitable, people nonetheless manage to thrive beneath its surface, in colonies founded by prisoners who threw off their chains.

Next after that is a blue and green planet named Equus. The jewel of the Ungula system, it is from here that most of this life originates.

Orbiting Equus is a silvery moon named Luna, in whose forested craters dwell the thestrals. It is named this after the reason all of these bodies have not crashed into each other.

Beyond Equus lies the red planet Bucephalus, rich in minerals and fortune-seekers alike. Honeycombed with deep tunnels, hives, mines, and nests, many thrive in his arid climate.

Furthest yet is the deep blue gas giant known as Tambelon. Shrouded in its clouds drift great leviathans and the derelict remains of an ancient megastructure. Its depths have not been plumbed.

Drifting among all of this is the collection of bodies known as the Umbre Belt. It is named this after the planet it once was. What few umbrum remain are now quiescent among the ruins of their home.

The star will not collapse, the planets will not collide, and the peoples will not perish.

Harmony willing.
