"By my troth! It is the witcher who saved us from woe!"
—Upon seeing Geralt
Delwyn of Creigiau is knight from Creigiau introduced during Blood and Wine Expansion for The Witcher 3: Wild Hunt. For the first time Geralt can meet him at the inn by the Tourney Grounds, where the knight vows in front of his lady. Delwyn promises her that he will either win the tournament or keep his mouth shut until the next tournament. There is also option to try fencing with Delwyn while training for real contest.
Later, during the vampire attack on Beauclair, Geralt can find run into Delwyn on one of the palace terraces, where the knight is trying to fight katakan. If the witcher does not help him, the knight dies killed by a monster.
