The Lower River Bank is an area in the south east of the Needle Hills region. It can only be accessed through the Gauntlet Swamp, and a pass in the south which leads into the Upper River Bank. It is split in two by a shallow river that meanders through the centre of the area. A path to the north east leads into Dragon's Graveyard.

It is not necessary to travel there as part of the main plot of the game. The only reason to go there is for the sector challenges.
