Leyline Navigator

Leyline Navigators are nightborne located at the Orgrimmar Embassy in Orgrimmar, and some of them can be seen leaving to Northern Barrens through the Talon Gate. They also appear in Silvermoon City, the Undercity, and the Nighthold in Suramar City following its liberation from the Burning Legion.
