Well, I did it! Got a full house (six players) on Sunday and ran for them for the full eight hours. Everybody said they had a good time and I am choosing to believe them. Due to the nature of Hero System combats (long) and player shenanigans (even longer) I never actually got to the boss fight, but my players did not seem to mind. Maybe I will run the other half of the adventure at another con. The characters that were chosen were: The Elven Knight; The Half-Orc Fighter; The Halfling Adventurer; The Wizard; The Cleric of Pelor; and the Baklunish Monk. The Paladin rounded out the party as control NPC.
