The floating baby is really cute from Adrian's standards as it seems that his face is a mix of his sister's and Lycan. If he was asked on who the parents of the Baby Erebus are then he would actually point to the two. This was an expected situation though as he learned that the soul that was pulled up other than Vlad Tepes was the fragmented soul of the Pricolici.
The Pricolici is none other than the species name of the original ancestor of the vampires and werewolves. Their race is still considered Asmodian, but the Pricolici is an Asmodian Erebian. He is also the original Asmodian Erebian that has descendants which were the Asmodian Vampire Vlad Tepes and the Asmodian Werewolf Lycaon Arcadia. He is the original ancestor of the two Erebian Species.
