Leon's two escorts guided him toward the northeast part of the town. They entered a small alley between two shops there. One was a tailor called The Queen's Maid and the other one was a small tea house called Agatha. The alley was so small that you have walk sideways in order to traverse it. At the end of the alley, however, there was a bigger pathway on the right, and capable of people walking normally there. As because the top part was covered by part of Agatha's building, most people would not guess that it was a secret passage and might only think of it as a door to the back part of Agatha.
The path was only half of Agatha's width and Mercurio who walked at the front touched the wood panel of the town's wall to which the building was attached. He pushed it and a door popped out, which was then being slid by him. Mercurio entered the secret path and Leon followed to see that it was a continuation of the first path which basically ran through the city wall.
