Jo Muncey was a terran who was seemingly in control, or at least serving on a terran starship. Although details are vague, it appears that, along with Nick Carpenter, she strayed perilously close to a black hole, despite warnings of caution from an outside source. Although the ship was able to break out of the black hole's gravity for a time, the ship was drawn into the black hole eventually, taking Muncey to whatever fate awaited her.
