The Varisian Gulf, or Varisian Bay, is one of the most prominent features of the Varisian landscape, providing the border for most of the western edge of the land. Formed when the empire of Thassilon shattered over ten thousand years ago, the Gulf is all the remains of much of the western holdings of the once-great nation. In modern times, few know of the Thassilonian relics that rest beneath the waves, yet the few remnants of the lost empire that still stand on dry land on the Gulf's edges, such as Hollow Mountain and the ruins of the Irespan in Magnimar remain as reminders of nations lost to the depths.
