Curdle (or Kerudas Karosias), and her companion Telorast, was a mysterious creature who possessed the bones of a dinosaur-like, bipedal reptile. The two suggested that they had been sent by Edgewalker but never elaborated exactly why.
As Fiddler conducted a reading of the Deck of Dragons in Letheras, Telorast and Curdle shifted into two Elder Eleint, destroying a tavern in the city. Much later, they encountered Torrent and Olar Ethil, swearing their allegiance to the former after the latter told them she had no need of the two.
Telorast and Curdle followed Torrent and Olar Ethil, rarely making a sound in the presence of the two. During the climax of the novel, as the Otataral Dragon descended to the earth, the two were able to shift into the form of two elder dragons, joining Silchas Ruin in defending the great dragon against the other Eleint. The two were not heard from again in the aftermath of the battle.
