The Forsaken Isles is a plane that has been cut off and forgotten by the other realms. Nobody outside of it knew it even existed until recently, when the Archfey Wrexis discovered it. How it got cut off from the other planes is still unknown, but right now its connection to other realms is unstable. There are many temporary portals all over the world where strange things come through. Wrexis is harnessing these portals to transport adventures form all across the realms to help her explore this world. This is how Driftwood Anchorage was born.
The Forsaken Isles is a plane that consists of mostly water with islands. The size of these varies greatly. Not all islands are explored yet. What shall the adventurers find there?
