From publisher blurb:
The Things Lost to Time is an OSR adventure that can easily be modified for any fantasy roleplaying game. It is an adventure for characters level one to three.
Deep in a mine is an ancient vessel. Something so ancient, it sunk under the stone like mud. A vessel alien to this world, yet here longer than most of human history. Can the players harvest its strange technological bits before being disintegrated by deadly lasers? Or will they be enslaved by the odd pink aliens which have been unleashed on the world?
This adventure requires a mouse-like mindset. Hide from the protectors of the vessel, or die. Monsters and hazards are quite dangerous, so a degree of stealth and cunning is necessary for the players to find their fortune.
