She aids Jason in his search for the Golden Fleece out of love, assisting
him with her magic and saving his life in several quests, playing the role
of an archetypal helper-maiden, before abandoning her native Colchis,
marrying him, and fleeing with him westwards where they eventually settle
in Corinth. Jason leaves Medea to marry princess Glauce.
In revenge, she murders Glauce and the king with poisoned
gifts, and later murders her own sons by Jason before fleeing for Athens.
