Adda of Temeria

Princess Adda of Temeria was a daughter of Medell, king of Temeria and queen Sancia, as well as a sister of Foltest, who became king after their father's death.

Adda and her brother had an incestous relationship that resulted in pregnancy. This child was cursed (presumably either by Ostrit, who fell in love with Adda, or by their mother, who was furious about the incestous union between her son and daughter) and both mother and child died just after the birth. Foltest ordered that the two be buried in the Royal vault beneath his castle in Vizima.

Seven years later, their daughter came back to life - but as a striga. The curse was eventually lifted by witcher Geralt of Rivia, and the young princess was named Adda, after her mother.

The game suggests that it was Ostrit and not their mother who cast the curse, as evidence by his journal.
