The Dragonwall Gate is a gate in Tear separating the inner and outer city. It is a hundred leagues or more from the Spine of the World.
Perrin, Faile, Loial, Gaul, Bain and Chiad exit in a hurry from this gate as the Stone shakes, scattering the Defenders guarding it. They travel from there to the Waygate to reach the Two Rivers.
