A hunter from a Hunter Earl family—that meant the other party carried a forbidden object.
Without Julius's reminder, David knew the strangeness and danger of forbidden objects. Those things' power could easily twist reality. They couldn't be viewed with common sense.
As for the "Xavier" Julius mentioned, David also knew about that—it represented a duke with overwhelming power in the empire, and the biggest supporter behind First Prince Charles.
This duke's family had already produced three generations of Hunter Earls. The current Duke Xavier was also currently the highest-ranking Hunter Earl in the empire.
No one knew exactly how many forbidden objects they controlled. Fourth Prince Roland, the Order, even the already-rebellious Duke Agamemnon all greatly feared this Duke Xavier.
However, obviously, the hunter appearing across from the station eyeing David wasn't a true Hunter Earl.
He just carried a forbidden object—that eye.
