Description
We came here to retrieve a reserve pylon to power Auchindoun's defenses, but we've been pinned to this position by the Shadow Council for hours!

I need to get these injured back to Exarch's Refuge, but we still need the backup system!

Please, gather Arkonite crystals and an Arkonite pylon from the tomb and meet me at the refuge as quickly as you can!

Trivia
The title of this quest is a reference to Blizzard's StarCraft franchise. In the StarCraft video games, a Protoss player is told that they must construct additional pylons when they attempt to build a unit without having the necessary amount of psi (supply), a resource provided by pylons. The phrase also became an internet meme.
