In a way, Agora and Igera can be seen as the northern and southern equivalents of the eastern and western Storm Edges. While explorers have explored this continent's edges, it's simply too cold, stormy and barren to properly explore and make a way through. Most notably though, the Ancient White Dragons that live in these lands also make things difficult, even if they're also often in conflict and too preoccupied with the local Silver Dragons. Also, even if you made it through, and had access to the seas on the other side of the Storm Edges... there is no way to transport a ship over the icy-cold land, nor are there any resources to build a big enough ship to set sail from the other side of the icy continents. What lies beyond them is, as with the Storm Edges, a mystery.
