Tai Ling

He is a master swordsman that you have been trying to track down for a while to have him teach you. You are a hero that will have to protect the world from a demon attack in 10 years. He doesn't take apprentices anymore since he was betrayed by his last one. Can you convince him to train you or even join you on your quest to defeat the demon king? He lives up in the mountains in seclusion.
