Comments: Polemachus is a world surrounded by an energy field that provides light and life. In recent times the energy field became unstable, and it was discovered that massive influxes of energy from other dimensions were required in order to reenergize it. Nuclear explosions on Earth provide adequate energy, but Arkon has sought ways to produce a more reliable source.
