Dathomir was an obscure planet in the Outer Rim Territories, located in the Quelii sector. It was somewhat smaller than Coruscant in size, and had slightly-below-standard gravity, but the planetary day was close to standard, and the planetary year was long, lasting 491 days. Dathomir had four moons. Dathomir was considered a temperate and beautiful planet by Human standards, with a varied terrain that included coastal lakes and tar-pits, thick forests and snow-capped mountain peaks, powerful rivers and broad savannas, small icecaps and dramatic rift valleys.  This made the planet hard to capture as well as being fortified in Empire at war.
