The innermost world of the Cularin system, Acilaris was barely large enough to be considered a planetoid. Nevertheless, it had enough gravity to hold an atmosphere, albeit one which was laden with sulfur, carbon, and boron.
The surface of Acilaris was too hot even for a ship to land, and was believed to be rich in natural minerals and crystals. However, the temperature prohibited mining activities. In 31 BBY, there were rumors of the droids of Uffel accepting contracts to design mining machinery able to withstand the local conditions.
