The mostly-human-and-halfling Burke’s World (a/k/a “The Planet Nobody Wanted”), in orbit around Choux, is a home to smugglers, pirates, and the like. It’s a small, harsh, dry dust world with no meaningful resources. In addition, the complexities of the Choux System make it difficult to get to and from Burke’s World without a good map or guide. It’s far from civilization, though not too far from Harmas.
There is one main city, known only as “the city,” on the planet. The party has also discovered a secret scientific outpost run by the aelfar Dr. Neova on the far side of the planet.
