Here's my description.
Krells'aire'nurudo (Sairen)
Sairen is young for his rank, though he doesn’t look it. He’s a handsome Chiss of above average height, slim build and azure skin. His formerly tight-cropped hair has grown out slightly during his service to the Empire in Exile, although it remains well within military standards. The dark uniform marking him as an ambassador is unwrinkled and pristine. His right arm is a cybernetic prosthetic up to the elbow. It appears to be a standard Imperial model, made of dark, exposed durasteel. His cybernetic right eye, while crimson to match his Chiss heritage, has a subtle hex-like pattern across its surface. He speaks with a refined imperial accent. His protocol droid "Titus" shadows him.
