Speak to Therazane on the Halcyon Egress.
Sadly, I must stay and hold the rift, so you will have to battle without me. Go now to Therazane and join the battle, as promised. You should find her at the Halcyon Egress, north of Lorthuna's Gate and east of the Scoured Reach.
When our part of the bargain is fulfilled, bring the last piece of the World Pillar here as quickly as possible.
You will also receive:
- 250 reputation with Therazane
