Kyrse is the son of Velg Lortnan and an unnamed woman. His mother died when the Mygorg first came to the Manor.
Starfire and her band of rebels attacked the Mygorgs who were punishing Kyrse for reading, which kickstarted the whole siege.
He encouraged his father to fight the Mygorg. Though he originally planned to go with Starfire and the rebels, he changed his mind at the last minute and returned to his father. Unfortunately, his father had set up a trap to try and convince the Mygorgs that he and Kyrse had, had nothing to do with the rebels, and that trap ended up killing Kyrse. He died in his father’s arms.
