Rock of Bral
It is said the Rock of Bral was one of the asteroids making up the Tears of Selûne, orbiting Toril behind it's moon, a city build upon the rememnants of a human pirate empire and before that countless, more alien, civilizations. This heritage is reflected in the meltingpot Bral now is with races from Mind Flayers to humans inhabiting the city in (relative) peace.

Wildspace, the final frontier, a place so enourmous it defies even the most detailed of maps. This may not match, to the letter, Spelljammer canon, but who can say how its has evolved since the earliest days of space travel?
