Jomark was one of six worlds in the Jomark system. Originally known as Bynas, it was absorbed into Xim's empire as he expanded his borders from the Kingdom of Cron. The planet was mostly covered by ocean, with one small continent called Kalish, and thousands of small islands dotting the surface. It had a population of 2.8 million spread across Kalish. These colonists lived by fishing and sea farming. The Yuuzhan Vong captured Jomark during their invasion of the galaxy.
