Caldera's Edge Random Encounters
This is the first that many will see of Caldera. Situated on the tip of the crater, this rugged region of badlands contains twisting canyons with crumbling rocks scorched red by the ever-burning sun. The wasteland stretches on for miles, with sparse vegetation and the local wasters clinging on to life. It is dominated by a TDA uranium mine that was buried under ash during Impact Day, as well as the surrounding crumbling infrastructure, which provides a dangerous (but potentially lucrative) salvage opportunity for savvy teams.
