Before leaving the island, Zaos healed the most dangerous wounds of the survivors; he couldn't do more since they didn't have time. While they did a lot of research, it was impossible to tell how much time they had left. Still, most likely, the followers of the demon god surely were planning to do something that would force Milliendra to summon him. According to Drannor, Milliendra had the power to control the elements as well, so the demons were no match for her, but she was just a child. She didn't want to kill anything, nor did she want to see others getting hurt. The demons will probably use that against her.
Zaos and Aleni said farewell to the kids and promised them that Milliendra would be with them once they returned… Once they headed toward the port, Zaos and the others found the smuggler that Aleni had asked to help. He had grown so much over the years that he had a fleet of eighty ships.
