Siridar-Duke Telemachos Atreides (d. 8015 AG) was probably a descendant of Nestor IV Atreides and had a rivarly against the House of Hajus Corrino. He was quoted as saying "If I can't have the bloody throne, neither can my quivering Cousine!" The Atreides clan supported Tiiopa'it Roonaladh in overthrowing Emperor Fredhrick IX. He was impeached before the Landsraad where he said in his defense: "Evidently I was wrong"; he was executed after two days of trial.
