Mutants in a fantasy world

[Tetsubo]

I've mixed Mutants & Magic in every edition of D&D. Heck I added magic (at least in small, controlled amounts) into all of my Gamma World campaigns as well. As someone else mentioned the Chaositech is a must have. I don't have my copy of D20 Future yet (shipped today, yeah!) but I've heard it should be handy. The newest edition of Gamma World might be useful as well.

When I saw the title of this thread I thought it was going to be about running an X-Men style game in a D&D world.

Anyway, comets are nice to use. They were often thought to bring bad luck. Another explaination could be the appearance of a bright new star in the sky. (The planet is bathed in cosmic radiation from a nearby stellar explosion) Or, you could make it the result of extraplanar meddleing. Maby some Far Realm cultists are abducting people and exposing them to the energy of the outer realm.

I had a feeling somebody was going to asocitae this thread with X-Men in some way. I really like the star idea, it allows foe a serious amount of myestery to what is happening. Not to mention it might even give me the chance to send my PCs into Realmspace.
