The River Mora is the river which forms the border between Shienar and Arafel. Its headwaters are located not too far westwards of the fortress of Fal Dara, and the river flows south and west for some distance before flowing into the Erinin. It passes by the Field of Merrilor, where the Last Battle is fought. The Mora is navigable from not too far from its headwaters, allowing relatively straightforward passage from the environs of Fal Dara to Tar Valon or parts beyond.
