Alster Grove was a human male who served as a lieutenant in the Imperial Navy. Grove was suspected to be involved in a plot to assassinate Darth Vader, and was summoned to Virkoi. The upcoming ISB loyalty officer Sinjir Rath Velus tortured Grove for two nights straight until he gave up the names of his co-conspirators. Following this Grove was dumped in the churning seas of Virkoi by officer Sid Uddra, while Lord Vader beheaded Grove's co-conspirators.
