We Must Construct Additional Pylons

“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!”
