I would go back to the amazons, or at least take the girls there, they would probably help the girls and it would be a good environment for them with no men. Then he could move on to find a place to set up base. As is he is wanted, the girls being with him will cause them trouble. As well as that while yes it will take some time for a next group to be sent, a ss rank party was lost, that wont be taken lying down. They will send a new group there expecting bandits. Though in a way that can be a befit. They will have to send some sss rank or numbers, which probably means a small elite group, who would be hard to have mind controlled. So when they get there and find the base cleaned and clearly not bandits, you may get a chance to tell what has happened to high ranking people for them to report back.
