Leon had been a strong and legendary hero, however he had also thought he could challenge the gods, after his failure to do so he was supposed to be executed, that was when instead he was given the job to serve a traveling mink deliver some scrolls to the west, however the downside to the deal was that to keep Leon under control, the monk has a spell called the light sutra, it’s connected to the crown around Leon’s head and would give him a large headache if he rebelled.
