Riome was a small ice world in the Dorvalla system. There were occasional patches of grass along the planet, as well as small creeks heated by magma underneath the surface. The Toom clan set up a hideout here after sabotaging Lommite Limited and InterGalactic Ore's freighters in 33 BBY, but Darth Maul was able to anonymously lead Patch Bruit and other LL workers to Riome, where they gunned down each and every Toom member on the planet. However, Darth Maul was waiting in the shadows, and himself took down the remaining combatants. The seas of Riome were home to thin, ribbon-like sea snakes.
