Ridu, a security officer serving the Galactic Republic, was assigned to Taris. During a Senator's visit, he temporarily took charge of Elara Dorne's Search and Rescue Squad 204. Tragically, the Senator fell victim to rakghouls because Ridu misjudged the perilous nature of Taris. Subsequently, Ridu held Elara responsible and submitted a report detailing the event to Captain Kalor in the Personnel Division. Upon learning about Kalor's investigation, Elara challenged Ridu on Taris, compelling him to retract his original statement by presenting substantial conflicting evidence about what transpired.
