Katchan was a world that was located on the edge the Outer Rim Territories. It is the homeworld of the Katchani, a species of pale green-skinned, elfish humanoids that are ruled by a monarchy. Katchan's surface is covered with forests, valleys, highlands and low mountains. The planet is actually made up of two large continents separated only by a narrow sea. Katchan sits on the Corellian Trade Spine near to the border of the Saijo sector.
