John Verdun is an NPC in The Witcher 3: Wild Hunt encountered during the quest At the Mercy of Strangers in Velen. Verdun was a former soldier in the Temerian Army serving in the 10th Maribor division deserting before it was destroyed by the Nilfgaardians during their invasion of the North. He fell in with a group of fleeing refugees but when they learned he had deserted the refugees tied him up and left him for drowners on the river bank.
Geralt finds him tied up on the river bank and must decide whether to leave him to die or free him without knowing that if freed he will hunt down and kill innocent refugees later during the game. While not a main plot driver, this quest and character serve as a warning example to the unintended side effects of the witcher's actions.
- In the German version of the game his name is Hans.
