He hadn't spoken at all till now, and that sign language mastery indicated that he was mute.
But more importantly, is he a false resonator? I didn't expect to see one who is experiencing a false awakening so soon.
But he probably doesn't realize it himself. And there's no knowledge about such info in most books. I heard it from the master after all.
And that Firm Will and Silent Combat must be the fruits of the false awakening. He's probably good at close-quarters combat.
Or even with weapons, given the fact that he is the princess's personal knight.
Hmm...
A princess and her knight, in love with each other...
Another cliche.
Given the tragic nature of their story and that ominous title, I could already guess how it would play out. Vance, the loyal knight, would probably sacrifice himself to save his beloved princess during some political crisis or final battle.
