i'm looking for ideas for a convention one-timer, i want something that wouldn't require the players to know too much about WHFR but that will give them something other then "just enoughter fantasy world", do you have any sugjestions? i'm thinking mybe some kind of intrigue or mybe investigation. and it has to fit into 4-6 hours.

what about exscavating the old "Enemy withing"?

Here are some suggestions that will give them good roleplaying opportunity:

1. Karls & Scents

2. Rough Night at the Three Feathers

3. False Pretenses

4. With a Little Help From My Friends

Most/all of these are available as downloads. You can find out their locations by checking here: dl.dropbox.com/u/167876/WFRP%20COMPLETE%20SCENARIO%20LIST%20AND%20DOWNLOAD%20LINKS.pdf

I would recommend "Journey To Black Fire Pass", the demo adventure from last years Free RPG day for WFRP, and prelude to the Black Fire Pass supplement. It is a great story, with a variety of encounters. It can be changed up a little if needed, but there is a great story structure and some great characters (PCs and NPCs).
