Dewstone Plains is a mostly arid region bordered by hills and rocky canyons to the west and by the ocean on the east. It is home to the first dungeon instance in the Nuian starting zone: Sharpwind Mines. It is accessible from the Lilyut Hills in the North, or from White Arden or Marianople in the South. Nuian armor crafting quests start here as well.
