Dark Sun / Castles & Crusades Part 2

The background for a second session of the now poorly named Dark Sun one shot:

With the Veiled Alliance still in hiding and part of Nicodemus' troops now under their orders, our unlikely heroes spent the last year wandering the desert, hunting and raiding villages like any other slave tribe. The tribe's scouts have brought word of an unlikely caravan traveling through the desert nearby - a supply caravan belonging to Sorcerer-King Kalak whose destination is unknown. The tribe has set up an ambush to take the caravan. Why is it out in the desert? What does it carry?

These are my goals/wish list for a second session of Castles & Crusades / Dark Sun:
1. Make use of the Slave army that now follows the party.
2. Have a mix of scene framing and dungeon exploration. But a bigger focus on dungeon exploration than in the last session.
3. More goofy minis!
