Her Highness the Striga is a main quest that begins at the start of Act V of The Witcher and wraps up when Geralt reports to King Foltest in the Epilogue. It moves through the Castle, Old Vizima, the swamp cemetery and the Old Manor. Princess Adda has turned into a striga again, and Foltest wants Geralt to lift the curse if he can, and kill her only if he must, after hearing out Triss, Velerad and De Wett.
Foltest won’t hold it against Geralt if Adda has to die, but the others pull in different directions: De Wett hints at a reward for killing the striga, while Velerad rewards Geralt with the sword D’yaebl if Adda is saved. The hunt leads from a false sighting at a tower to a chapel in the swamp cemetery where Adda sleeps by day. In her sarcophagus Geralt finds the journal of Ostrit, who cursed her the first time, proof that someone renewed the curse on purpose. That someone turns out to be De Wett, whom Geralt must kill at the Old Manor.
