The Valley of Fallen God's I

We make our way out of The Holy City and onto the main road. I didn't have to get scanned since I'm leaving. I see what they are doing now. They are scanning men with magical devices. I don't know what for, though. "There is no way they'll find the son doing this! This is a colossal waste of time!" A man from the back of the line yells the answer to my question. So they are using some magic face scanner to find me. It must mean they got a sketch of me somehow. The only thing I can think of is when I was fighting that horde of monsters on the borders of Perla.
