There are five known connected pairs of orbs in Azeroth and Outland. The first and most-often used connects Sunfury Spire in Silvermoon City to the Ruins of Lordaeron in the Undercity, which were implemented to allow blood elf players in Quel'Thalas to travel to the "mainlands" without having to venture through the Eastern Plaguelands. Alliance players cannot use this orb. This is probably to prevent easy raids on Silvermoon City.
The orbs are also used in single buildings to connect from the ground floor to the top. Such locations include Duskwither Spire in Eversong Woods, Falcon Watch in Hellfire Peninsula, the Sun's Reach Sanctum on the Isle of Quel'Danas, and the Kael'thas-controlled Firewing Point in Terokkar Forest.
- According to Mathias Shaw, the one in the courtyard of Lordaeron is a gift from the blood elves. In case of emergency, he would use it because he can at least attempt to negotiate with the blood elves, unlike the abomination guards.
- Once a player has completed the Battle for Lordaeron scenario, the orb connecting Silvermoon and the Undercity can no longer be accessed from the Undercity's side; the orb is non-interactive, and curious players will almost certainly be killed by the blight. The orb is still active from Silvermoon, now transporting players to Zidormi's side, safely overlooking the charred battlefield in Tirisfal. Speaking to Zidormi will allow the player to travel to the past, before the Undercity's fall, which will reactivate the orb.
- During the early beta, the two orbs between Sunfury Spire and Undercity were actually two blood elves named Peoreth and Maltrake.
