Aralicien

Aralicien doesn't speak. He's silent, and more than just silent in his voice, his movements also seem too ... quiet. Like his feet should make more of a sound when they touch the ground, his breath should rasp in his throat, but it doesn't.
He's silent, and there's something off about him - so other dragons stay away from him. Like a magnet, he just repulse them, push them away - not by doing anything actively, but just because he's offputting and something about him screams 'get away, run!'.
His eyes are also silent. They never seem to move, or rather, his head never moves. All movements are slow and calculated, he seem to hear everything and can react appropriately, but his head never turns to look at or hear what is talking or making noise. He just quietly hears, and then reacts.

In the clan, he plays music.

He's a really good musician. He doesn't sing, for obvious reasons, but he can sometimes be found humming though that might not be the right word for it - its more of a slow, deep rumble eremitting from beneath his skin. Not a sound you could possible make with normal vocal chords, something deeper, more like an incoming earthquake.
He might be talented, but the clan still stay away - there's something eerie about him
