The Tryll are a creation of Mordain le Tisseur de Chair, which live in Kresht Rhyll. They are rodents and are quite adorable, straddling the line between rabbit and hamster; however, they also have poisonous flesh, a venomous bite, and an astounding reproduction rate that is only held in check due to the harsh conditions of the forest in which they are found.
Should a number of these creatures ever manage to spread to Brelande or beyond, the menace they could represent is unfathomable. For this reason, both the Pacte de Znir and the Protecteurs des Bois react violently to anyone found trying to smuggle them out.
