The Kingdom of Destruction (DQB2 fanfic)

Legend says that one of the mighty kings of this land will bring the long-awaited doomsday. The kingdom has a rule everyone feared to break. No creation of any kind. If anyone were to break this rule, the best thing to happen to them was to be beheaded. Two builders navigate this cruel place, spreading kindness and hope to the people they meet. However, the prince found out about them and is hunting them down with his chief advisor. The builders hoped to be able to change the land for the better before it was too late, even if that change seemed minuscule. Will they succeed, or will they die trying?
