Deep Harbor District was a Guard District in Port Caynn in the third century of the Human Era. It was bordered by Lowdown District to the north, Tradesmen's District to the east and South Hills District to the south. To the west lay the harbor. Coates Lane and Dockside Road were two main streets in the district, Ashlie Lane could also be found there. Both Ladyshearth Lodgings and Nestor Haryse's house were located in Deep Harbor District. All in all it was a safe area. But still Rebakah Cooper and Achoo managed to find and capture three child stealers there, when they went after Aldis, Vorna's daughter.
