I ran SoA years ago in second ed. and thought it was a pretty fun adventure and now, looking at the wonderful social combat rules we have, I'm thinking about a significant rework to turn it into a stand-alone adventure for some advanced social characters. I'm not putting anything on paper right now because I want to finish Castle Drachenfels and make that a decent adventure and not just half decent and half finished.
Here's some of the block of ideas I've had about it so far:
1. Start the adventure off outside Altdorf and let it work it's way back. (which is obviously important from a story point of view, if you've read SoA, but basically any of the adventures from any of the books would be a good springboard.)
2. An advanced and packed "social calender", just because the PC's are in city, doesn't mean we give them a chance to put their feet up. They need to be chasing plot hooks by day and schmoozing by night, with a lot of racing through the streets and desperately trying to get across town in between.
3. Start the adventure with a loan being thrown at them, or make them go to one of a series of banks around Altdorf with a need to find some hard cash quickly, they haven't time to wait for someone's stipend to come in next month, they need cash, for clothes, lodging, booze and other schmoozing supplies NOW.
4. The clue cards from another post mentioned would be particularly handy, since there is a lot of information flying around, they'll need to be able to process it all.
5. Since we're having it stand alone, it makes much more sense to have a slaanesh cult, or vampires, or both, looking for the artefact, rather than a khorne cult, which will stick out like a sore thumb.
That's all for now, if I sit down to start writing this I'll let you know! T+S welcome!
