Disaster / Destruction
Deep within the Darklands, in the Temple of Tharzduun, the Master Glyph was destroyed by the Guardians of Golarion. This prevented a second Age of Darkness by stopping a giant asteroid from striking Golarion. While the main destruction was narrowly averted, some debris still rained down. Most of it struck uninhabited areas, but several tons of rock rained down on the ancient dormant volcano located on the surface directly above the Master Glyph. The city of Cauldron, located inside the dormant volcano, suffered catastrophic damage.
