We got a chance to get back to the Keep on the Borderlands and the Cave of Chaos today. They cleared out one cave system and high-tailed it back to the keep to report on the growing threat. The characters took some time to heal, regroup and restock.
The NPCs that had been travelling with them will come back, the Cinco Hermanos (the Keep is modeled in my game after Spanish missons and castles, so everyone in the Keep speaks Spanish). They have also picked up a couple of other characters. An assassin pretending to be a thief, a healer (NPC) and a Forester (or maybe an Unseen). The Healer and the Unseen are classes from Magical Theorems & Dark Pacts. The wizard of the group is going to drift more towards Pyromancy so I am going to let my son use the Pyromancer spells from Astonishing Swordsmen & Sorcerers of Hyperborea. This will work out well since I am gong to start drifting towards my "older, bolder, colder" world that AS&SH supports.
They have not run into Dr. Zabaza yet, but I'll keep you all posted!
This group doesn't have a name yet. I'll need to figure something out.
