I've been brainstorming and am thinking of an idea based loosely on a classic roger corman SF/horror flick called "Galaxy of terror".
NO, I WILL NOT HAVE A' RAPED TO DEATH BY GIANT MAGGOT' SCENE IN THE SCENARIO!!!
The idea is the players are sent to rescue a team of scientists that were investigating some ancient site (Not the traveller ancients, another lost ancient race of advanced beings.) and discover the site was a type of "rite of passage" for the ancients, where their youth went to basically satiate their primitive urges until they were no longer interested in them, at which point they were mature enough to receive a measure of power and responsibility.
The site still functions, and even works with humans. Most of the scientists are dead, having died thru excessive indulgence. One survivor seems to have overcame his primitive urges and has been given vast knowledge and some power by the site. He claims he'll be of great benefit to society, but should the players take him home?
That's the gist I have so far, I need to put some meat on the bones. I mean, I have a story, now I need some parts where the players get to do stuff. And a title...
