Chinquix was the skewbald prowlgrin mount of Rook during the events of Freeglader. His previous owner was Graze Flintwick, a Freeglade Lancer who was killed at the Battle of Lufwood Mount. After the loss of his master, Chinquix became temperamental and unstable, not allowing anyone near him. Despite this, Rembit kept him out of respect to Flintwick. The only individual who Chinquix felt comfortable approaching and befriending was Rook, who used On the Husbandry of Prowlgrins to learn how to look after prowlgrins.
