Jad Karadin is a witcher of the Cat School who had decided to retire from the profession and live out his life as a nobleman in Novigrad. He married a woman and adopted her two children. Karadin formerly led a band of assassins, of which Selyse, Lund, Hammond and Vienne were members. Whether there are more former members alive at the time Karadin is encountered remains unknown.
The witcher Lambert, whom Geralt of Rivia encounters shortly after taking on a contract for an ekimmara issued by one of Lund´s guardsmen, has a personal interest in finding Karadin since he has credible information that the now-disbanded gang had killed Aiden. Aiden, a witcher of the Cat School, was a good friend of Lambert who now tries to find Karadin to exact revenge for the murder of the fellow witcher. Lambert eventually manages to track Karadin down, with Geralt's assistance.
It is revealed that Karadin retired from being both witcher and assassin and lives in Novigrad as a merchant and has his own family. He tells them that Aiden's death was an accident and that he greatly regrets it.
In the end, Geralt of Rivia must decide whether he helps Lambert follow through with his revenge or if he does not want to back Lambert in his decision, sparing Karadin despite the death of Aiden. If Geralt decides to help Lambert, a fight will ensue in which Karadin will meet his end. If Geralt chooses to take no part in Lambert´s revenge, he tells Lambert that "he may do with Karadin as he wishes", but he will take no part in it.
