Fast reference for my character, Onyx
He's an important part of Carnelian's story) He's a slave too and belongs to Carnelian's master, so this boys are kinda neighbours

Onyx is not noble, before becaming a slave he was a dancer at traveling artist's troupe. He's really good at dancing and gymnastics, and very flexible)
But because of old wound (just look on these scars on hic neck) he can't talk, scream, sing... he has no voice at all and so he communicate with other people with gestures, drawings and facial expressions
And he's very calm. Mister pokerface)

Onyx is a tanarr (my closed species)
