Gaidar Vai is tall, but thin of build. He has milky pale skin, and open, clear facial features which could be considered rather attractive. His long, black hair hangs lank and messy about his head. He darkens the area around his eyes with dark makeup, giving him the appearance of deep exhaustion, or perhaps the state of the newly dead.
He dresses only in black robes, very formally at all times, sometimes with small accents of red.
He has a high, nice-sounding voice, but often with an unpleasant scratchy undertone. His eyes are an icy blue. He rarely smiles, and when he does it resembles more a snarl.
