Extensive canyonlands to the east of Dzagon - infested with inhuman tribes and other dangers.

Dzalana is an unexporable region northeast of the Wilderness of Bahdza. Little is known of this area, but it may well be the homeland of the Harpies and Hekets that Prince Ahmtur the Mighty is constantly having to fend off.

Whatever the case, this area is, for some reason, listed on maps in the same font and size as the Sulfurous Wastelands, the Sea of Sorrows, and the Ruins of Orr.

The Guild Wars 2 Wiki has an article on Dzalana.
