Tachys is a tall, broad-shouldered dhampir with alabaster skin, sharp, angular features, and pale, icy eyes ringed in black that carry a constant, predatory focus.

Once kept as living livestock by the vampire Aster, he was drained night after night until his identity nearly vanished, only to be freed without explanation. Now bound to an unending hunger and a faint psychic tether to his former master, he survives through ruthless restraint and chosen violence, determined never to belong to anyone again.
