Wyverns are the smaller, non-fire-breathing relative of the Khadrim. They are prevalent in the Vastmark principality where they hunt in the Kelhorn Mountains, preying on small animals or large, wounded ones. Wyverns have a snake-slender neck, membranous wings, dark scales, and spiked wingtips.
Wyverns communicate with other wyverns by emitting a shrill threnody of whistles to communicate with other wyverns. They travel in pairs and defend their mates to the death.
