Humm! I probably haven't been active enough on the boards, or on wizzies, enough for me to carry much weight around here. But I did take the time to read through... most of this thread, so it became impending that I comment..
It's been -my- observation that every storyline thus dar, ultimately pitted the heros up against some villan, or society perhaps, regardless of which it appeared that someONE was responsible. Perhaps it's time to take a look at new enemies?
Like I mentioned earlier I haven't exactly been showing up all that much, TSR has lost a lot of its luster with me, but that's a whole new thread altogether! In anycase, this may have been done, but maybe you could explore the options of... maybe a parasite, or disease. Maybe subtle, it'd have near no symptoms, but eventually drive you mad, and violent, maybe a little more volatile, in the more literal sense, maybe it'd melt your flesh off! Could be that the moonbeams began sweeping not only people, but objects right from their planted position and throw them God knows where? Something of that accord I'm sure has happened already, but basically, look for something, natural or unnatural, that is the stronghold, the supports to order that mankind (but not limited to) used as their foundations... and then knock them over!
