River of Swords
This long river forms the border between Mulhorand and Unther. It is divided into two portions: The Lower Swords, which flow in two parts from their sources to their junction by the ruins of Sekras, and the Upper Sword, which flows from Sekras to the Alamber Sea.
The Lower Swords are named the Blue Sword and the Green Sword. The Blue Sword River lies entirely in Unther and has as its source a fresh water spring in the southeastern portion of that country. The Green Sword River flows from its source in Azulduth, the Great Salt Lake, and carries a considerable amount of salt with it. The Green Sword is undrinkable.
From the junction at Sekras, the river flows northward to the Alamber. This water is bitter but drinkable, and it carries a lot of sediments. A machine that pumps the river and filters the salt still operates at Sekras, though none but a handful of priests of Thoth know its workings. The river floods in summer time, though it is somewhat less predictable in its floods than the River of Spears, which lies to the east. Large, flat-bottomed boats carry cargo between Unther and Mulhorand settlements on either side of the river, and a canal bypasses the pumps and allows access to the upper river.
Sekras is a small city. It was once the center of the cult of Sebek, but now it is infested with werecrocodiles. Paladins in the service of Osiris, with the tacit approval of the priests of Horus-Re, destroyed the city and scattered the inhabitants. Alongside the upper river are many small farms. The lower river is mostly uninhabited, except for hermits and wizards who choose to sequester themselves from the control of the priests of Thoth. This area is known to be the home of a number of sphinxes.
The River of Swords was given that name because it was here long ago that the god-kings of Unther and Mulhorand laid down their swords and swore an oath of eternal peace between the two kingdoms.
