Rethinking the Plague Worlds

I really am not a fan of how Zeb's guide handled the plague worlds. I think the UPF would have worked to help those people once the Blue Plague was under control. <br /><br />That said, I do like the idea of a place that's so dangerous, that it is placed off limits. It would open up some really cool adventure opportunities:<br /><br />1. A Zombie Apocolypse? Perhaps a settled world with a highly infectious outbreak...<br /><br />2. Riddick - Pitch Black - an alien so dangerous that it wiped out every attempt at colonization<br /><br />3. ?
