Obtain 8 Orders from Kael'thas from demons at Manaforge Ara and bring them to Spymaster Thalodien in Area 52.
Performing quests for the Scryers will cause your Aldor reputation to decrease.
As you may have noticed, there are servants of the Burning Legion all over Manaforge Ara. Kael'thas has entered an alliance with the Burning Legion. He must've caught wind of Illidan's descent into insanity and switched paymasters accordingly.
If the Scryers get definite proof of this, it will give them a considerable political advantage. I know for a fact that the Legion forces at this manaforge have orders that bear Kael's seal.
Get these orders and bring them to Thalodien.
You will also receive:
- 12,650 experience
- 75 (if completed at level 90)
- 250 reputation with The Scryers
