A yrthak resembles a huge spiked pterosaur with vast leathery wings, 20 feet from head to tail and weighing 1,500 pounds. Its horned snout is long and narrow with a brightly colored crest on its head. Its eyes are tiny and almost useless.
The yrthak's signature ability is its ability to emit powerful sonic blasts from its maw in the form of a lance of pure sound that can rend flesh and explode rock and stone. The creature is effectively blind, unable to see anything more than a few feet away, but makes up for it with its ability to "see" by sensing sound and movement. Yrthaks are immune to sonic attacks.
Habitat and society
Yrthaks hunt alone or in small clutches of up to six. They are more intelligent than mere beasts and are capable of speaking Draconic, but have no apparent interest in forming societies. Yrthaks are exuberant hunters, wildly blasting their prey with sonic lances. Yrthaks cover wide areas in search of prey, resorting to scavenging only in times of extreme hunger.
A fur-covered, black-and-white-striped subspecies known as the boreal yrthak inhabits the arctic wastes of the Crown of the World. It emanates a glowing blue and green aura of electricity that blurs its form and makes it difficult for prey to detect in flight, but also hinders its ability to hide on the ground.
