The Calappidae was a ship, probably a hovercraft, called "the Grey Ghost" by the crew. One of its crew members, Maggie, is the mother of two children who decide to find her in the Matrix as a birthday present for her. They accidentally alert the Sentinels to the position of the ship. The Sentinels broke through every bulkhead and blockade the crew members set up. Parr's head exploded. One last crewman tried to run for the EMP but the nearest sentinel grabbed his arm and impaled him inches away from the button. Lena and Rollins, jacked in the Matrix, died, and Maggie was last.
