He claims to be a bard, but you never actually see him with an instrument. It could be a ruse. In fact when you do see him fight in the r46 Story Quest, he uses small throwing daggers.

We've already seen plenty of the unreleased classes in the game via NPCs: Musketeers, Arcanists, Mystics. There is even apparently a Shephard's Guild in Falcon's Nest.

Could he be another of the unreleased classes, Assassin?

What do you think?
