In The Witcher computer game
Zoltan mentions her now and again in the conversations he has with Geralt and others. Her exact relationship with the dwarf seems to vary during the game. She definitely is described as being "his woman", but whether or not they are married or simply betrothed is not clear.
Following the uprising in Vizima in which Zoltan assisted the Scoia'tael, Eudora's Father put an end to her engagement with Zoltan saying that he did not want a 'rebel firebrand' in the family.
