From Whence They Came

Eidolon Watcher Abilities

Find and Banish the Crystals

• Head southwest from the Shadow Vault down the path toward the Weeping Quarry. The crystals are large purple structures floating on pillars, easy to spot.
• Approach a crystal and use Banish Scourge Crystal (button 6). It channels for about 10 seconds. You need to destroy 10 total.
• Crystals respawn in roughly 30 seconds. You can camp 2-3 crystals and rotate between them without needing to search the whole area.
• Your shade starts in Ethereal (stealth) by default, so you can largely avoid combat. However, Hungering Plaguehounds can detect you at close range, so give them a wide berth (or feed them for An Undead’s Best Friend credit).

Efficiency Tips

• All three Eidolon quests overlap in the same area. Work on all of them simultaneously: banish crystals, feed hounds, and assassinate Restless Lookouts as you encounter them. You can complete all three in 5-10 minutes without moving much.
• When finished, use “Leave Vehicle” instead of running back. It teleports you directly to Keritose Bloodblade at the Shadow Vault, saving travel time.
• If your bar addon (Bartender 4, etc.) hides the Eidolon ability bar, temporarily disable it. Alternatively, you can use /cast Banish Scourge Crystal as a workaround.
• Avoid running directly through enemies even while stealthed. Sleeping hounds and large groups can still detect you at close range. Use Phase Jump to hop past dangerous clusters.
• If you aggro a plaguehound, you cannot feed it while it’s attacking you. Your Blood Siphon is too weak to kill it efficiently, so use Dephase to break combat and reposition instead.

Lore Context

Keritose’s focus here is the Weeping Quarry, a massive saronite mining operation southwest of the Shadow Vault.

The Scourge is pulling “immense amounts” of saronite ore from the quarry, and Keritose wants to know what they’re building with it. Keritose guesses at what the crystals are rather than knowing, saying he assumes they are defensive structures of some sort, not unlike ziggurats, the signature Scourge defensive towers from Warcraft III. Destroying them clears the way for Ebon Blade gryphon operations in the area.

Saronite itself is the crystallized blood of Yogg-Saron, the Old God imprisoned beneath Ulduar. Mining and working with saronite drives workers insane, which is why the Scourge uses mindless undead labor.

If you look into the water at the bottom of the quarry, you can see one of Yogg-Saron’s maws, a small environmental detail connecting this area to the broader Old God threat.
