The Damocles Inquisition
As far as anyone is aware, the Northern lands are covered in a vast mountain range, spanning the entire top half of the Doras Isle.
Many ships have circumnavigated around the coast, to try and find any bays or areas on which to dock, but the sheer mountains and cliffs make it impossible.
Likewise, many explorers have attempted to climb the mountain over the Blackvein Mountains themselves. They’ve either returned, worn and un-successful, or not returned at all.
