Background

 * You can't step on these bugs.

''The mighty amber trees of the Dread Wastes have long been a crucial part of Mantid society; the Mantid farm and harvest the tissue of these trees, which they use to build structures throughout the Wastes. One of the greatest and largest of these trees, Zan’vess, towers over the small ridges south of the Briny Muck – and its imminent sha corruption endangers not only the local Mantid who rely upon it, but all those they might attack in their resulting madness.''

''To end the threat, you’ll need to take to the skies, destroying the wavering energy fields that protect the great tree while being blasted by the mantid’s natural defenses. After your aerial assault, you’ll break through insectoid monstrosities and battle to the tree on foot, where you’ll fight face to mandible with the mantid guardians who’ve dedicated their very lives to Zan’vess’s protection.''

According to Rear Admiral Zigg, this island contains the last remaining forces of Grand Empress Shek'zeer that are protecting a large weapons cache that Garrosh would like to retrieve for the Horde. Coincidentally, Sky Admiral Rogers would like to prevent that from happening by confiscating the cache first.
