Greenheart Caves

These tunnels were discovered when the ice melted on the northern island as an extension of the small "hollows" which littered the Wastelands before. As it turns out, these were the mouths of many caves, all filled with lush plant life and a geothermal heat that never seems to abate, even in the harshest winter. If you go far enough, these caves connect up to the Stardust Caves on the southern continent.
