Immortal Dragonmark

This is a world called Atheran. A thousand years ago, the dragon clan and an allied army of other races repelled an invasion from the Abyss, but the dragons were nearly driven to extinction in the process. The last traces of dragon blood were scattered among the descendants of the various races in the form of “Dragonmarks.” Those who bear a Dragonmark are potential “Dragon Knights,” but fewer than one in ten thousand ever awaken their power.
