These mythic space wanderers are a part of the lost civilization's technology adapted by humans, although without the full understanding of its principles. These ships have unparalleled mining ability, stealth shields to avoid detection during interstellar travel, and their weapon systems can defeat a star fleet. A ship of this type has autonomous mining vessels that detach themselves from the mothership to gather GRVX because the ship’s titanic mass generates its own gravity field that can destroy a planet at a close distance.
