What’s known of the phenomena is that the Mars Crater has ghouls in it and a lot of magic barriering around it. A lot of magic supplies are found/grown in, and smuggled out of, the crater. Assuming this isn’t the only potent source of magical phenomena on the planet, it stands to reason that somewhere out there is a treasure trove.
Recently, many of the illegal off-grid harvest ops run out of Heliopolis have gone silent, and there are rumors of a number of missing citizens. This has lead to a drying up of the flow of local magical supplies to Mars City, raising the price, as Earth imports are increasingly relied upon. An investigation sponsored by a prominent Mars City talismonger concluded that the primitivist group Olympus Prime was behind the damaged supply lines. The recent destruction of Heliopolis in a ‘natural disaster’ has once again slowed the supply, however.
