Thanks for the pdf. I'll give it a read over in the next day or two here.
If I end up running something in the second time slot, it will be one of two things (reader's choice):
1.) A group of time traveling Victorian gentlemen of fortune have gone to the last days of the Roman Republic in order to prevent the assassination of Julius Ceaser. Why? Because they don't think it's fair that Brutus gets the blaime for the act. Steampunk+Sword & Sandles+pulp= commedy gold, or at least it was that way in my head. D20 Past (which is basically d20 modern with 20 pages of alternate rules).
2.) A young Lordling and his loyal band of adventuring comrads have come to his dying father's side. Unfortunatly, not only is dear old dad, about to become dear old deacased dad, the adventurers arrived not even a full day in advance of a horde of orcs who intend to take the land when the lord dies. The PCs must hold the castle until help arrives. That's of course assuming the messanger got through. What do you mean you didn't send a messenger? I do hope you have something clever up your sleeves. D&D, core only, no psionics.
In either case, players would be level 6th, and I would make pre-gens. If there is a character concept that you are particularly keen to try, then by all means let me know and I'll do my best to accomidate you. Otherwise, you take what I hand you.
