The acidified planet Jina is widely considered as an uninhabitable hell hole. Despite this, a hardy mining colony known as Aram’s Ravine persists underneath the heavy clouds. Most travelers and traders in these parts choose the luxury resort moon Cala Duriha instead, and only the most desperate descend through the toxic atmosphere to visit the Ravine. Fate forces the PCs down to the planet, however, where the plot soon thickens around them.
