The party returned to find the Iron Cup fort in lockdown mode. Too many people had gone missing and they weren't letting anyone in or out without express permission from Tovosia. So the group decided to spend the night on the Satyrdance, anchored at the shore.
They set sail at first light for the southern tip of the southern-most island. With Josian by their side, they hoped to incapacitate the pirate crew by spamming Sleep. However, as they sailed down the eastern shores, they were once again distracted by an interesting sight. A massive rock formation with steam billowing out of the base where the stone met the sea. The steam seemed to be coming out of shore-level caves. Once the party was sure the caves wouldn't flood and drown them and that the steam wouldn't boil them alive, they entered one.
