Although Fleets offers violence for all interested, that is still only one part of the game. One of the reasons for mankind to populate the Pleiad star cluster is the abundance of helium-3 encased in asteroids. This scarce resource is what makes warp-drive technology and interplanetary travel possible. As such, it’s an important economic factor in the Pleiads. The new escort ship, the Refinery, is specialized in obtaining this resource, represented in the game by spending energy to get money. The refinery is big and has a decent strength as well.
