Reroll: Back to the throne

What happens if young and promising, but really wayward king dies in an accident? Distant relatives start strifes, trying to claim a free throne, kingdom plunges into chaos and Death, which was about to go to the vacation, goes mad because of the amount of work. Is there a way to fix everything? Making a deal with Death and becoming almost immortal while trying to get your castle back in exchange for some spoils of war sounds totally legit!
