Emerald City. It didn't have alien armadas filling the sky, or mad gods trying to turn it into a Hell on Earth. Things were stable - until the Silver Storm tore through the city and unleashed a flood of dangerous super-villains and monsters! Now criminal masterminds have cast aside years of fragile peace, ready to go to war to settle old scores and claim the throne of the city's underworld. Emerald City has no established teams to call on in this crisis. It is a city that needs heroes. Will you answer the call? A brand-new setting for your Mutants & Masterminds Third Edition campaign set in the same universe as Freedom City, Emerald City provides a home base for your heroes and a place they can shine.
