The Battle of Rhen Var was a battle fought in 26 ABY during the Morsian-Yuuzhan Vong War. The planet Rhen Var was an ice planet and uninhabited, which led to the Morsian Empire choosing it as one of the main fortress worlds of their Finibus Galacticus defensive lines, specifically the Finibus Thanium ad Ashicus around the Tion Cluster.
