Corin of Galman arrived at Cair Paravel by ship in Year 2 of the Golden Age, swore fealty to all four Pevensies in sequence, and was handed a ruined watchtower above the Shribble and forty retainers as his entire inheritance. He carries the Compact of the Marches and the foreknowledge that the centuries between this Age and the Long Winter test everything built now. Treaty Memory retrieves agreements the living have forgotten. Alliance Web maps every political thread running through the contested margins where dwarves, centaurs, and creatures who were promised peace are still quietly testing it. He resolves the boundary dispute both sides had stopped discussing because neither could admit being wrong first. He starts with a drainage problem. Lasaraleen finds him strange in a way she cannot diagnose. Lucy noticed him in the first week. The North will need to last. He is building it to.
