The Great Rain of Fire occurs on the world of Mystara. Caused when the civilization of Blackmoor detonates some great engine or weapon, it releases a blast of energy so intense that it knocks Mystara off its axis and spreads devastation across the globe.
Fire, burning debris, and great waves of arcane magical energy crash through the Burnt Gate on Eamon, causing localized destruction and widespread magical disruption. The Talus Assembly immediate study the event and learn from it.
