The Lords of Prey are an evil race of raptors that live in the mountain clefts of Natalia, such as the High Bleaks. They prey upon rabbits, and thus both races hold each other as mortal enemies.
Over the centuries, the Lords of Prey were a constant menace to rabbit civilization, although the point by which they had fully developed as a race of rabbit-killing antagonists is unclear. By the time of the reign of King Jupiter, they were largely subdued.
By the events of The Green Ember, King Jupiter had been slain by Morbin Blackhawk, the leader of the Lords, and the kingdom of the Thirty Warrens had fallen into decay, once more at the mercy of the winged menace of the mountains.
