The Quaking Fields (quest)

Objectives
Speak with Slate Quicksand at the Quaking Fields in Deepholm.

Description
Before you can help us here, you're going have to deal with Therazane, the Stone Mother's, forces to the south. The elementals and giants upon the Quaking Fields are being mustered.

They too are after the middle fragment of the World Pillar. They'll attack us amidst our war with the stone troggs and we'll be unable to repel them.

I've sent the arch geomancer ahead. Get to Slate Quicksand and do as he asks.

Rewards
You will receive: at max level

Completion
Good,, you're here.

We'll have to act fast if we're to prevent Therazane's forces from attacking.
