The Drekk are a new breed of Dragons, created by Schalos. Unlike Dragons, Behemoths and Wyverns, Drekk stand on their hind legs, and use their front legs, which have been adapted, as arms and hands. They retain the same method of bearing offspring, the usual passing down of knowledge to offspring, and the ability to use Dragonfire.
Drekk have a unique ability, their hide strongly resists Dragonfire. This allowed them to slay thousands in the Massacre at Crest.
While they stand on their hind legs, they're not fully upright like Dracokin are. Upon Schalos' request, they have been allowed to stay in the larger Dracokin cities in Dutha Crest, namely the metropolis located to the north, Crest.
