Four-legged reptilian predators found primarily on Tython, horranths typically hunt in large family groups called broods. With their high birth rate, quick maturation and few natural predators, the horranth population is usually constrained only by a limited food supply.
If food suddenly becomes more abundant in a region, a horranth matriarch will lay hundreds of eggs, causing her brood's population to explode. As their numbers multiply, the beasts grow bolder and more aggressive. Unchecked, the brood will continue to spread until they finally exceed their food supply, at which point the matriarch will suddenly stop producing eggs. Unfortunately, this return to normal population levels typically only happens after the brood has thoroughly devastated the region.
