S3 'Expediation to The Barrier Peaks' by Gary Gygax is one of the most lethal adventures I've run in the past. This module presents a very interesting idea not only are the surroundings of the campaign world being infected with invasive species but Greyhawk has it's monster population boosted. But could player's PC's make it aboard the starship Warden from the Warden Science vessel?! Bare in mind that we're using the Castles & Crusades system to play both of these adventure and the Starship Warden campaign.
Let's say that the player's PC's overcome the lethal encounters aboard the Warden science vessel & that they make it to the transporters aboard. Some science or engineering officier has hard wired the transporter circuits to an unknown destination. The party wants to take a one way trip & ends up onboard the generation ship the starship Warden.
