Duke Grandfather, the most famous Nuisance Man to walk the streets of Capital City, made a promise many years ago. Now, he's lived a good, long life, and is enjoying his golden years with his beloved Lilly, the most powerful necromancer the Capital City Watch has ever known.
But that voice in his head, the same one that had guided Duke to his Ultimate Weapon, is back, and it's time to fulfill his long-ago promise. The problem is, it's a trip he won't be coming back from, and Lilly insists on going with him.
What starts out as a journey from which they won't return quickly takes a turn when they encounter a mysterious being in the forest, who claims to be Death himself. Lilly is taken away, and Duke has no choice but to return to Capital City, where he becomes embroiled in his own adventure to save one of his last remaining friends.
Will the two be able to complete their quests and reunite in time? Or will Duke be forced to take the Gun back to the dragon himself, leaving Lilly and everyone else he loves behind to mourn him?
