Though Megalopolis has many superheroes, none of them is quite like Fantazia. That’s no surprise, given her parentage. But immortality is hard, even for a sorceress. Watching loved ones age and die…? It’s better to live in a pocket universe tending bar. It’s safer to remain cold and aloof, to not get attached to anything or anyone. So, helping the Elite Hands of Justice defeat the Dragon was a mistake. Her father’s band of shiny, happy do-gooders with social lives right out of a soap opera gave Fantazia a taste of camaraderie – and of something else. Hanging around their mysterious ally has birthed a new threat, something worse than the evil plot of the city’s newest super-villain. The true peril is Cyrus…for he threatens Fantazia’s heart.

WANT. That is all.
Me, too, lass. Alas, we must be patient…
