Strange currents and tides affect this river, for although the river most certainly runs from the north-east down to the ocean in the West, it has been known for people to be swept upstream. Whether this is a result of the magic of the Masters of Scorpion Swamp, or whether the innate magic of the swamp is to blame is unknown by scholars. Within the swamp the Foulbrood is almost impossible to cross save via a great stone bridge, known by some as Eagle's Bridge.
- In Scorpion Swamp, the Foulbrood River flows west to east. In the map of Khul in Titan - The Fighting Fantasy World, the river flows north-east to south-west.
