Yrvolth and Tyrrleigh

Yrvolth and Tyrrleigh are known as the Twin-Drakes, or the Tvinndreki. They are presumed to be the parriarchs of the Blue Dragonflight and served as commanders underneath Kaszastrix in Aedenhal while the Kingsbane Drake turned southward. The Twin-Drakes commanded the Centaurs in this invasion. The horsemen suffered a significant defeat and left the flight's command during the Tvinndreki Struggle, and the flight itself was defeated in Vestal with the aid of Aedenhal's Jezis after they fled southwards.
