In order to conceal the Paxans' existence from intruders, they terraformed a protoplanet within the system. If an intruder were to come within their territory, they would be confronted with an apparent wormhole, in actual fact, an energy field, which would stun the ship's crew and place them in a state of biochemical stasis. The ship would then be transported out of their space. The intruder would then regain consciousness, assume the wormhole was responsible for their altered position, and depart.
