Ventus is born from a union between a vampire and a spring nymph, turning him into a hybrid called "Ymbrine" a specie that manipulates time which chooses a safe place—Arcadia—and same day to create a time loop and preserves the last 24 hours. Female Ymbrine's are common but the male ones are very rare because they tend to have stronger powers that are unmatched. And because Ventus's father is a vampire, he is also a quarter blooded vampire-kind.
