Quest:From Whence They Came

Objectives
Keritose Bloodblade at the Shadow Vault has sent you to banish 10 Scourge Containment Crystals.
 * Banished Scourge Crystals (10)

Description
My main concern is the Saronite quarry down the path to the southwest. They are pulling up immense amounts of ore from that quarry and I'd like to know what they're building with it. To that end, we'll start by weakening their defenses.

I noticed a series of crystals scattered throughout the base and I assume they are defensive structures of some sort, not unlike ziggurats. Use the Eidolon Watcher to destroy any of those crystals that you find.

Progress
Are those crystals out of the way? I don't want them to prove a nasty surprise for my gryphons.

Completion
Excellent work. We should have little threat in the air then.
