Nivellen

Nivellen was a cursed man who lived in Redania, near Murivel, in a manor.

Early Life
When he was a boy, Nivellen was sickly. His father and grandfather had made a fortune by leading a gang of miscreants and cutthroats, and Nivellen rose to command them after his father was killed with a blow from a two-handed sword.

One day the gang robbed a temple in Gelibol and had Nivellen rape the young priestess there. She spat in his face and cursed him to be a "monster in a monster's skin", and then killed herself. Unbeknown to Neville and the gang, the woman was a priestess of Coram Agh Tera, the Lionheaded Spider A couple of days later, Nivellen's form had changed, though his mind and personality had remained untouched. The people in the house fled while Nivellen raged, in panic, and the house obeyed his whims, the doors banging shut and the furniture flying.

Cursed
Nivellen stayed in the manor, alone, for a long time, until one day he espied a man stealing a rose from a rosebush outside in the yard, remarkable blue roses from Nazair. Hoping for a cure to his state, Nivellen demanded the man to give up his daughter. This led, ultimately, to girls coming to live with him for a year each, and leaving at the end of the year with gold and gemstones. Then along came Vereena, who Nivellen thought to be a rusalka, but who in reality was a bruxa.

Resolution
Geralt of Rivia's visit to the manor brought him in contact with a man who was no monster despite the way he looked, and the two parted on friendly terms. The next time they met, Nivellen ended killing Vereena, who had attacked Geralt. In her death, though, she broke Nivellen's curse because she truly loved him.

"A Grain of Truth", a short story included in The Last Wish collection, details the tale of Nivellen.
