The Azure Passage is a narrow strait found on the eastern end of the Sea of Kings. It separates the continents of Impatria and Jalafar from one another, although the two continents are technically still connected by the Shattered Isthmus.
While few trade routes travel through this part of the world, the Passage provides a reliable course for those that do come through its waters. It most notably provides a sea route to isolated regions such as the Savage Lands and Estlan.
