Post Greyhawk Wars: 585 CY
The waters of this great eastern river drain almost all of old Aerdy and is navigable for almost all its length. The Thelly is likewise navigable, although its own tributary, the Grayflood, is too shallow to permit anything larger than a canoe or small barge to travel on it. The Mikar rises from the Gull Cliffs and the Lone Heath and is a slow-flowing, shallow, broad river, little used for trade. The Imeda also rises from waters below the Gull Cliffs and is only a minor trade tributary to and from Rauxes.
