The fourth zone contains the remains of a planet destroyed either by celestial collision or an ancient core explosion.
Debris makes navigating this hazard difficult while the exposed resources make it quite profitable. Both automated and manned mining operations are scattered throughout the planetary remains extracting raw materials that are delivered to the local Z4 Crucible Outpost.
Rumors persist of strange sightings within the debris field. Accounts vary from strange lights to fully formed figures watching crews work. None of these rumors have been validated with actual data.
