Defeat some Devouring Earth monsters
The Devouring Earth are of the most dangerous threats the city faces right now, and without heroes fighting them at every turn they could wreak unimaginable damage and destruction. Heroes such as yourself need to keep the pressure on them by defeating the Devouring Earth's minions at every turn.
The Devouring Earth are trying to extend their reach into several areas. Fighting them anywhere they appear would help. If you're looking for a place to go, I'd recomend that you look in Terra Volta and Talos Island.
