Tomb of Horrors in Space?

I mentioned a while ago that I was thinking of putting together a session of Traveller based on the old Dungeons & Dragons module Tomb of Horrors. I thought that it would be fun to mix it up a bit and do a sci-fi dungeon crawl, and it was. Now this post will contain a few spoilers for anyone who isn't familiar with the Tomb of Horrors should be wary. It is available updated to 3rd and 4th Edition D&D so you might find yourself playing it one day.

To convert the module I had a look through and decided that I only wanted to use the first half of the Tomb. There were a few reasons for this. The first was that I only wanted this adventure to last one evening. These guys are space farers, they don't want to be stuck in a dark underground ancient tomb for very long without good reason. The second was that Traveller characters are fairly squishy and the traps and combats become pretty deadly in the second half of the Tomb of Horrors. You can't just find a cleric that's willing to raise your dead crew mates. They are dead and it's back to character creation and a session to introduce the new character into the story.

Next I had a think about how to handle the magic. This is science fiction, there is no magic unless you include psionics so everything had to be technological. This limited some things and a few had to go. I kept one of the teleporters though. The fact that there isn't any teleportation technology in my galaxy made this significant. read on...
