A failed assassination attempt was made on Si-Di-Ri, the President of the Tiss'sharl League, by a Tiss'shar assassin approximately eight months following the Battle of Yavin. The assassin did not succeed and managed to flee.
Before the attempted assassination of Si-Di-Ri, Geor-Dan-Thi, a Tiss'shar politician, became Vice President after the deaths of Mayor Antha-Kres, Secretary Lai-O-Sid, and Vice President Astre-De-Kay under suspicious circumstances. Numerous individuals, including Si-Di-Ri, suspected Geor-Dan-Thi was behind their assassination.
