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 theirs fangs and injecting a venom that kills the baby inside.

Makenna is the undisputed head of her pack-within-the-pack. The Undead have always been regarded with deep mistrust by the living, so she and her fellows keep to themselves. Though not related, she considers them to be her kin and is fiercely protective of all of them. Not that they really need it: they sleep during the other dragons' normal waking hours and are generally left alone. That alone will not change Makenna's attitude though and she will be wary until the bitter end.
