Wehttam, found in the Core Worlds' Wehttam system, was a planet. It was the original homeworld of the Wehttam species and resided in the Farlax sector.
Situated along the Widek Bypass, the planetary body became part of the New Republic seeking safety from the Yevetha. Subsequently, the Wehttam, along with the Fian, turned on the Yevetha, handing them over to the Yuuzhan Vong.
