Windhalm of Attre (1240 - 1267) was the prince of Attre. A chubby youngster of 12, born in the year 1240, he was one of the young men that visited Cintra to vie for the hand of Princess Pavetta and was chaperoned by the knight Rainfarn. However, due to a turn of events he didn't win the young princess' hand.
7 years later, when he was 20 years old, Calanthe arranged an engagement between Pavetta's now 6 year old daughter, Ciri, and Windhalm to ensure an alliance between the two regions as Attre had a strategic value to Cintra. However, this was called off 4 years later thanks to Pavetta influencing her mother.
Later in 1267, now around 27 years old and a duke, he led a rebellion in Cintra against Nilfgaardian invaders, but was ultimately captured. Emhyr var Emreis, the emperor of Nilfgaard, wanted to make an example of him and ordered his public and spectacular execution.
