Kull

From Inheriwiki, the ever-growing Inheritance database

Kull are especially large Urgals. Kull are born as Urgals, and through their growth, they grow progressively larger until they are above eight feet tall. They are then called Kull. This happens, according to Urgals, because the 'Old Blood' flows in their veins. Siblings of a Kull may not be a Kull, though it is unclear why. They can run for days without rest, and keep up with horses. Galbatorix had several hundred under his comand before the Battle under Farthen Dur, and a group of them pursued Eragon and Murtagh through the Beor Mountains. Nar Garzhvog is an example of one.
