Sargath River

The Mystical teal, gray river flows not downward but from in almost a circular motion with the northern part running east to west and the southern part running West to east, this river is a conjuration anomaly that connects Skullport to many caverns around the world, the Riverborns are in control of this river and can close specified gateways at will, but they cannot create new ones. No one knows exactly how its controls work since the Riverborns were always the ones who directly managed it. The three known linked locations are a cave on the Ezmerleda Coast, a beach west of the Sangar Peaks, and a lake outlet east of the Golden Spire Peaks. Additionally, the Sargath River provides air from the Surface to Skullport, this is in contrast to the other parts of the Underdark which employ portals to the plane of Air, this may be a small difference, but it still has some implications.
