Shipwrecked!

Heres another idea for you. Armus from TNG's Skin of Evil, or something like him. A being that has the ability to reach-out and touch something. It doesn't need to be compleatly evil, it could just be lonly, misunderstood, etc...

Oh and Passageway is worth it's weight in latinum (sp?).

Kosst, have you considered running such a "Shipwreck" style adventure as a character development scenario?

In my USS Dauntless campaign, I ran a scenario in which two PC's (the Male Human Conn Officer & Female Vulcan Ops Officer) ended up making a forced shuttlecraft landing on an ice planet and having to survive while awaiting rescue - a fairly standard Star Trek situation going back to The Galileo Seven. However, what made the scenario of interest to the players was the level of interaction that they could bring to their characters, given that they had a decidedly 'Spock-McCoy' relationship but with marked sexual/romantic undercurrents to it - a bit like Tom Paris and B'Elanna Torres in the first few seasons of Voyager ... and look how that ended.

It was also fun for the PC's still on their starship to watch/listen to the level of interplay between the stranded characters (who, by the way, are husband and wife in real life).

Why not give it a try?
