- "The Noble Greylancer:"Who taught you the bow?
Arrow Belsen:"A traveling bowman."
The Noble Greylancer:"The wicked bow skill...Fewer than ten Nobles are known to practice if."
- ―Lord Greylancer and Arrow's conversation[src]
Master Slade is a traveling bowman who taught the wicked bow skill to Arrow. From Arrow's indications he is a human. His origins are unknown. His known range exceeds Arrow's by his admission. The Arrow's dream is to have the skills passed down from him be recognized by the Nobility. It seems like most students he reveres his master with the highest respect.
