Cataclysms are the most unpredictable element in Xemerys. There's no telling how or when they will strike. Their effects are truly powerful and will affect the entire world.
Rulers who prefer to stay on the safe side can acquire a Cataclysm Defender and protect their city for 24 hours. An active Defender will make your city-state immune to all cataclysmic effects. Cataclysm Defenders can be acquired at any time, even during the cataclysmic strike. A Cataclysm Defender must expire before a new one can be acquired.
