"This is Silence," Azerus announces as she leads you into a garden. "He's a little strange, and I'm not sure exactly what type of Mystic he is; he looks like a butterfly, and he's mute. Mesarthim's terrified of him; she's sure he won't talk to her because she's offended him, and nothing you can say will convince her otherwise. But he really seems to like music, so Asellus put him in charge of this part of the tour."
At this point Silence steps out from the shadows beneath a nearby staircase, and the reason Azerus compared him to a butterfly becomes obvious; he has huge butterfly wings and a pair of antennae. He smiles and waves as he walks up to you.
"Another human taking the tour," Azerus explains. "Wants to hear some of your music."
Silence nods and pulls out a harp. As he begins to play, his wings move, resulting in music; you'd heard of a pair of fairies in Devin who could do this, but you'd never seen anyone else try, and this man looked more like a warrior than a musician. You guess that there must be some Mystic magic involved, then shrug and sit down to listen.
