Crashed UFO

In this adventure, designed to last for a 3-4 hour session, the player characters encounter (or are directed to) a mysterious object in the mountains: A strange, silvery disc around one hundred feet across.

If they make it past the deadly laser turrets and the very hungry sole survivor who lurks inside the only viable entry, they can explore the derelict craft. They will find several magic items, including a solar-powered laser pistol, as well as evidence of the ship's dead masters: The brain-eating illithid. But with technology comes other ways to stay alive over long periods of time, and the greatest danger is accessed by pushing the only lit button in the entire ship...
