Memoir of the Final Ten Gates

Jaeho woke on the registration floor with his future still in his head and his younger body shaking from the shock. He had died at the last raid after his own guild turned on him, and now he had been returned to the past with full memory of every dungeon layout, traitor, and boss trick. He wrote a farewell he never meant to send, then started hunting the last ten gates on a private list. A class crystal in his jacket, a hidden scroll in his vest, and a device in a desk drawer all pointed to a path he had not seen before. He could clear a gate with cold patience, but he still flinched when his hands remembered the end. The man who offers help first is already tied to the old betrayal.
