Vocation Of The Dead Dragon

After the Zodilra kingdom's strongest magic knight is killed by his best friend, and the kingdom itself is taken over by a paranoid tyrant, it falls into a dark era of isolation for over twenty years. When a young woman stumbles upon a bland grave and calls the residing skeleton into her service, she unintentionally ignites a spark of hope. They may just be the key to ending the wretched reign, but the skeleton might need a little motivation first.
