Corpsicum

Corpsicum is a rare material that forms when the water of the Tarakeshi River flows through the burial site of the kaymos people in the city-state of Candares on the planet Castrovel. The substance has been very profitably mined by the Astral Extractions mining company ever since their technomancers discovered a magical use for it. The mining of the material is controversial as it is seen as a desecration of the dead, and the practice has even lead to groups like the Wallkeepers to attack the mining robots who work for the corporation.
