Rica was one of the first members to join the Sith cause and the first Sith Lady to sit on the Council. She was usually quiet, but at times, unleashed her rage upon unsuspecting victims. While she did not help as extensively as Ryric, she did have a hand in helping with the creation of the First Code of Conduct.

In 39 ABY, she assisted others in attempting to take over the Sith in the Ryric Rebellion but was killed in combat by Council loyalists.
