From publisher blurb:
'Visitors' is a quick-adventure for a party of four 9th level characters. Very little adaptation should be necessary to use in any campaign setting.
Encounters, Treasure, and other system specific information can be found in the compatibility packs freely available with this adventure.
Adventure Background
Visitors is a unique adventure that can take place under nearly any circumstance at any time. This adventure is a bit tongue-in-cheek, and is more appropriate as a one-shot, or a humorous diversion. However it could be rolled into a unique and very memorable adventure set if taken seriously and properly.
The adventure begins when the party becomes victims of abduction. During the evening, or perhaps at camp or another unique situation finds the party waking up inside of an alien spacecraft. Their weapons and armor remain, but they are locked inside of a room.
Players could potentially escape with the right spells. However, Alien technology is just as mysterious as magic. Teleportation, plane shifting, and any other method simply does not work while on the ship. At least not until the party finds the means to disable this.
