Hall of Ten Thousand Bones

For three thousand years, not a single dead person on this continent has ever found peace.

The gravedigger's son. No battle aura, no magic. On the night his family was slaughtered, he hid beneath his father's coffin, clutching his father's skull, and heard the first words of his life: "Kaier, survive. The sword is... beneath the third stele."

From that day on, he gained an ability: touch a bone, and he could hear the dead person's final words preserved within it and learn everything they had mastered in life. Others cultivated through talent; he did it by digging up one body after another.

He moved the bones of the dead into his own body. That hall was called the Hall of Ten Thousand Bones. One stele, one bone, one life. With every new skeleton, he gained another teacher and another debt.

By day, he had to travel, stay alive, and fight the battles he was meant to fight. At night, dozens of people spoke inside his head, telling him the things they had left unsaid in life. He couldn't reply to a single word.

The Church called it an evil art that desecrated the dead, and the Saintess was ordered to take his life. But after seeing the Church's Well of Ten Thousand Souls beneath its halls, the Saintess fell to her knees and asked, "If God is wrong, then what has my life been for?" Then the two stood side by side, journeying from a border city to the front of the alliance of all races, and from a rusted broken sword to an artifact capable of cutting down the divine throne.

Three thousand years ago, who locked the gate of death?
