There is a collection of systems in Galaxy Z-026 known simply as The Wastelands. Ravaged by the energy flares created by the Central Cataclysm (S.T.A.R.'s detonating of the North Star, containing the power of almost a million suns), these systems have become nigh uninhabitable, even by upper immortals, energy clouds so dense they tear apart any matter they touch. However, their is a material known as 'Coel', which can be used to power magic without need for channelers. This material cannot be synthesized nor created, native only to this system after the Central Cataclysm.
Any mining operations must be done without planet splitting. Releasing bursts of energy bigger than a weak atom bomb will detonate at least one energy cloud, shredding you smaller than even quarks. However, older methods are okay, including small blasting operations.
Beware for the Spots. Areas with so much energy packed into one beam that it is eternal, and will, like the clouds, shred you. You can see them as solar beams.
FTL is not recommended, as you could end up within a cloud, or the energy usage could detonate a cloud.
