Tristan helps arrange a tryst between Gargeolain and his brother-in-law, for which Gargeolain’s husband, Bedalis, later tracked Tristan down and mortally wounded him with a poisoned lance. When Gargeloain saw her lover killed, she fell down dead.
Eilhart von Oberge tells the same story, calling the lady Gariole.
