"Ghostgate is the gate citadel of the Ghostfence Ordinator and Buoyant Armiger garrisons. Ghostgate sits astride the only gap through which the monstrous hosts of Dagoth Ur might emerge from Red Mountain to threaten the rest of Morrowind. The Ghostfence itself is a colossal magical artifact that completely encircles Red Mountain and prevents the Blight from spilling its corruption across the rest of Vvardenfell."
