Trolls are one of the intelligent species. Trolls age in reverse. They are mentioned in Lodestar. Their leader is Empress Pernille. Empress Pernille was one of the leaders that attended the summit at Lumenaria. She is said to look like "a cross between a sloth, a pot-bellied pig, and a small child, with fuzzy skin, an upturned nose, and a short chubby body dressed in a purple tutu" (Lodestar, page 606). However, this is not how all trolls look because Empress Pernille is an older troll. It was also mentioned in Exile that trolls do not value animal life as much as elves do.
