The necromancers of Idyll Tower are not as the stories tell. Nobody sacrifices maidens or dances with death, they just study books and spells. Clarence, who has always lived there, loves its peaceful atmosphere, but Hazan, who has travelled to the outside world, is beginning to get bored. But when lethal poisons start to appear across Marabilia, both decide that somebody has to find the antidote quickly, and they must leave their peaceful home, even if the cost is their own selves.
