As wizards and witches begin to awaken in beds that are not their own, they soon discover three things. One, they are in a vast, strange city which seems to be utterly devoid of life. Two, their wands are missing - and so is their conventional magic. And three, as a bit of a consolation prize, they've each been gifted with a single power subject to its own limitations.
Telekinetics. Firestarters. Shapeshifters. And more. All from different times and places, different lifestyles and occupations, with one thing in common: they have no idea how they came to be in this place.
Fortunately, there is a man calling himself the Master of Ceremonies, who claims responsibility for their current state. Now they will have to learn to cope with a different sort of magic, with starting their lives over again, with each other...and with the Dark Menace, a strange, shadowy evil that the Master of Ceremonies has brought them here to combat.
As some of them will instantly realise, they have just, in effect, become superheroes.
