Quintilius, but known by most as Q (which he also prefers), is the son of 10, or Guinevere Hathenae the leader of the military presence in the immortal alliance as well as one of 6 remaining immortals. Q hates being "Royalty" he hates parties, large groups of people, people in general, and being recognized by basically everyone in the whole alliance doesn't help that at all.
 
While Q doesn't have social anxiety he much prefers the company of his knife sharpener, or gun cleaner, and especially reading old books. Q has a fascination with magic, he wants to understand as much as he can but it's pretty frowned upon by his mom considering he "should" be focused on his missions and protecting the people.
