Before Benjamin arrived, he had actually pictured many ways to deal with the rebel soldiers.
Obviously, the ideal method would be to hoodwink them through talk and just abandon them at Ferelden, so that they could seek asylum or find shelter in Carretas. But this would be rather difficult to pull off. Although the leader was very fond of him, he might not fall for Benjamin’s trick.
As for directly wiping them out through force, Benjamin just could not bring himself to do it.
Thus, he decided to act like a psychic and threaten the pitiful leader with some fictional tales. Fortunately, these people were not smart enough to see through his lies.
"Quickly leave this place and head to Carretas." Benjamin nodded and said as he looked at their flustered faces, "At your current strength, it will impossible for you to deal with the army from the City of Snow."
He had hoped that the leader of the rebel soldiers would obey him like before, but unfortunately, things were not so easy.
