Kayfer Deerborn (b. around 205 HE[1]) was the Rogue of Corus until Rosto the Piper challenged, killed, and succeeded him in May of 246 HE.
He only appears in Terrier, although he is also mentioned briefly in Bloodhound, when Rebakah Cooper and Clara Goodwin are discussing Pearl Skinner and comparing her to other Rogues. His name then is misspelt as "Kayfur"[2].
When Beka first encounters him, Deerborn is described as too old for his position, as he isn't any longer up to the job of keeping order among the city's thieves. Instead, his only concern is staying on the throne and getting even richer than he already is. Thus he doesn't care for the people obedient to him as he should.[3] He keeps his throne by buying the loyalty of the chiefs and the higher-ups in his Court. However, Corus experiences an influx of young people from other areas, like Rosto and his two friends Aniki Forfrysning and Koramin Ingensra, who disapprove of Deerborn.[4] His position by 246 HE is so weak that Crookshank even dares organizing a raid on Kayfer's Court and searching it top to bottom for his missing grandson, Herun Lofts, and Deerborn doesn't dare harm Crookshank as an response to the raid. After the Dead Men's Riot in May 246, Deerborn is found murdered and Beka realizes that her friend Rosto is responsible.
Physical description
His short brown hair is thinning. Kayfer has very blue eyes with lines around them and a "smooth arch of a nose". He is wearing quite a bit of jewellery: a black pearl drop of the size of a thumb in one ear, a silver hoop in the other and a gold ring with a sapphire of the size of a pigeon's egg on his right index finger.[1]
