The remote moon Rugosa was located in the galaxy’s Outer Rim Territories close to the planet Toydaria, a world in Hutt Space, which was the homeworld of the Toydarian species. Sometime before the Clone Wars, a large calamity boiled Rugosa’s oceans away, leaving the large skeletons of the coral behind.

The moon had a temperate climate, and parts of its surface area were covered by large regions of coral forests, with the corals varying hugely in size and some being large enough to support small starships. Cavernous valley areas also existed on the moon.
