Vampire dragons are members of the undead. They sustain themselves by drinking the blood of others. It is said that they are only "alive" at night, and seem dead or asleep during the day, as they cannot endure sunlight for long periods of time. Vampire dragons can only reproduce by changing the eggs of other dragons, puncturing the shell with their fangs and injecting venom that kills the baby inside.

The younger of the vampiric brothers, Akaratlan is much more reclusive than Nosophoros, holing himself up in Musica's cave and outright refusing to come out and speak with the rest of the clan at times. Despite this debilitating trait he is very observant, easily picking up on people's feelings and intentions. He is extremely grateful to Aaralyn for giving he and his brother refuge and to Musica for accepting their takeover of her previously quiet cave; any threat to either of them would have to reckon with an enraged vampire coming for their throats.
