The system will be Whitewolf, all the characters will be mortals, and the setting is the Wild West. Preferably, the character concepts will either have a reasonable purpose for being part of a wagon train or a band of outlaws- that still allows a lot of leeway.
This session will be BYOD (bring your own dice) and any books that you have for the WW system. If you'd like to come, let me know, I'd prefer not to have everyone and their mother show up though, because huge gaming sessions don't work out so well.
