Have you ever found yourself looking for a break in the middle of the Nerubian Kingdom? If so, in The War Within, you can take the High Hollows Carriage to tour the High Hollows area of Nerub'ar without any guards bugging you.
The carriage, which accommodates up to two players, roams around in a loop in the southern area of Nerub'ar. While riding it, all Nerubian NPCs become neutral to you, so they won't disturb you in your stroll.
