The Edda River, the farthest eastern river in Alagaësia, was a river that stemmed from the Eldor Lake and lead to Ceris. It then continued east to where Âz Ragni flowed into it. Orik, Arya, Eragon and Saphira traveled up the river to reach Ceris. Then the group traveled on the Gaena River. It eventually wends beyond the Beors and into the Eastern Reaches wending past Dragon Riders Academy located next to Mount Argnor and onewards. It also acts as a trading ground between the Dwarves, Nomads of the land, Wandering Tribes and Dragon Riders, the Dwarves transporting goods by the Edda River.
