Into the Wreckage

From publisher blurb: After several uneventful days of westward travel, your group has discovered an unusual protrusion in the relatively flat wasteland. Your field glasses reveal a large metallic object partially covered in years of dirt and sand. Strange markings on its exterior remind you of the stories you've heard about the League of Free Men, a pre-apocalyptic organization known for its unified government views. The group was also known for their vast wealth and technological capabilities. What is this object and why is it in the middle of nowhere? More importantly, has it already been looted or does it still contain valuable ancient technology?
