Dishi'ra Kolar was a Zabrak female Sith and offspring to Darth Matas and Yevra Sey and the younger sibling of Sirak Kolar and the older sibling of Maris Kolar. She was trained, as her brother, from birth as a Sith on Kroprulu. Dishi'ra enjoyed trips to Iridonia. She learned to become an excellent pilot and know military styled tactics in combat. She knew Teräs Käsi but did not master it. After she had been promoted from Sith Apprentice, she was renamed Darth Ricas. As her brother, she was respectful, and obedient and unlike many of the Sith, she never once thought of betraying a fellow Sith.
