Wyrsan (singular: wyrsa) live in the Ebonbane. They're dog-like creatures, smaller than wolves, with a distinctive howl who live in high mountains above the snow line. They are prone to killing frenzies and can tunnel under the ice as fast as they can run over it. A pack of wyrsan is called a ravening and will eat any flesh or carrion. Their young, called kitlings, are reared in a ravery. Jame and Marc come across wyrsan in Dark of the Moon.
