The party was hired as the exploratory group in a large, costly expedition to Lustria. The Lustria setting lent itself to an easy conversion of orcs to lizardmen and kobolds to skinks.
The party somehow managed to take the most violent route possible through the first level of the megadungeon. In the end, they confronted the mad dwarf king, his skink minions, and the giant spider. It was the very last hour of the convention, and I didn't know if I had the mental capability of running a mad dwarf king. I seemed to do OK even though the party decided to attack him. The final battle was brutal, but the party survived.
I look forward to running a continuation next year with as many repeat players as possible. I have the map and the characters, and they can start back at the entrance "the next day."
