I'm interested in running a scenario for my group that involves being caught in a burning building with a large crowd of NPCs. No monsters, no enemies, no "traps" just the hazard of fires, falling debris, panicked crowds, etc. Most likely it will involve helping NPCs survive as well, since simply getting out won't be that difficult.
Anyone have any ideas, advice or experience with this? Any modules that do a good job with something similar that I could draw from?
I've read up on smoke dangers, heat, catching on fire etc. in the "Environment" section and just need a way to tie it all to together so that it's exciting, dangerous, challenging and really outside the norm of "there's a monster, attack!"
All help appreciated. Thanks.
