The Nevermore is a scavenger, attacking weaker looking ships and abandoned hulks. The crew wear signature black and brown spacesuits.
They picked on the wrong ship recently and suffered a hull breach. Of 35 crew members only 16 survived, including Captain Jex. Most of those died when Brace took the ship. The survivors are likely vengeful.
The ship itself is a sleek black dart, much smaller than the Starlight.
