Description[]

Mission text: We have discovered that the Sphere Builders have been conducting operations in other universes. They aren't just looking to make changes in time, but in other dimensions as well.; Their experiments in the parallel universe have produced results that will aid them in forming Expanses here. We need to travel to that reality and stop the Sphere Builder research... while we still can.
