Ye Ye, an orphan who was taken in by the previous Gatekeeper, appears to be simple-minded but harbors an extraordinary ability to sense the supernatural.
After his master dies under mysterious circumstances, Ye Ye, unaware of the full scope of his master's legacy, becomes determined to uncover the truth. With the secrets of the ancient Night Gate weighing heavily on him, Ye Ye is forced to flee his home as the dead begin to rise and chaos spreads.
On his journey, he encounters forgotten ruins, haunted tombs, and strange beings. As he pieces together the clues of his master's death, Ye Ye discovers that the truth about his own past is far darker and more complex than he ever imagined.
