Windhalm of Attre was the prince of the Duchy of Attre. A chubby youngster of 12, born in the year 1238, he was one of the young men that visited Cintra to vie for the hand of Princess Pavetta. He was chaperoned by the knight Rainfarn. Later, as a young man of 24 and a duke, he lead a group of rebels in Verden against Nilfgaardian invaders, but was ultimately captured. The emperor wanted to make an example of him and ordered his public and spectacular execution.
"Windhalm of Attre... Order him to be beheaded. No... Not beheaded. Executed in some other way. Spectacularly, lengthily and cruelly. And publicly, it goes without saying. A terrifying example is necessary. Something that will frighten others."
