70590 Airjitzu Battle Grounds
At an unknown point in time, he was among the students taken under Yang's teachings, with Yang becoming infamous for his strict methods on him. However, unbeknownst to the public, he was secretly trapped in his temple, and after his death, were converted alongside his fellow students and mentor into ghosts. Yang then enslaved his former students, making them mindless servants to his will.
As the morning came and the curse on Yang's Temple started to take effect on the Ninja, he showed himself, revealing the student to be chained up, as he was imprisoned by Yang. The Ninja then quickly fled to the entrance, not wanting to suffer the same fate as him and the other students. They manage to reach the entrance, but Cole dropped the scroll mid-way and thus had to go back in to retrieve it, which caused him to turn into a ghost. Fortunately he escaped the temple before he can meet the same fate as the students.
