'Avatar: Seven Havens' Theory: Korra’s “Cataclysm” Could Solve the New Show’s Biggest Mystery

The new Avatar: Seven Havens series picks up about 225 years later, in an era when Korra herself is treated like the boogeyman: a mythical villain from the past blamed for triggering the "Cataclysm" that destroyed the world. In this post-apocalyptic world, the remnants of humanity subsist in seven isolated Havens scattered across the wastelands, constantly ravaged by storms. Benders are becoming increasingly rare, and the spirits who flooded into the physical world during Korra’s lifetime are conspicuously absent.
