I am a bone miner at the lowest level of Broken Scale City, and I survive by digging veins of divine bones.
But there is something sleeping inside me that can awaken the ancestral dragon.
That day in the mining accident, I came across something I shouldn't have touched - a still beating dragon's heart stone.
Now, all the aristocratic families in the Seven Lost Cities are looking for me and regard me as the "key" to unlock the seal.
But they don't know that I am not only the key...
He is also the only one who can lock that door again.
