Mars City Shadowrun
A group dedicated to cleaning up astral space and manahazards around the world. They received a significant chunk of their funding from Dunkelzahn’s will. They often work with DIMR to identify, isolate, and treat astral damage and other issues.
Rumored to have established multiple “astral sanctuaries” of unknown location and purpose. One exists in Chicago at Sanctum (the former Field Museum), and is home to many free spirits. Another possibly exists at their main Chicago base in Elemental Hall, but it is only open to initiates and is impossible to assense from outside.
