Tavell Geen was a male who served as the leader, or Scrivinir, of the Centrality for most of the Galactic Civil War and several years afterward. Little is known of Geen. Prior to becoming Scrivinir, he earned the prestigious title of Ottdefa from the University of Lekua V. Geen was outed from office in a bloody military coup by Centrality Fleet Admiral Sris Lehhett in the galactic turmoil not long after the beginning of the Yuuzhan Vong invasion. He managed to flee with his life to Coruscant where he tried to drum up support among the New Republic for his reinstatement.
