Csulok at World of Raids has published an article about his endeavors in The Wyrmrest Temple, which is located in Dragonblight. (Northrend – Wrath of the Lich King).
Wyrmrest Temple is the huge titan building in the middle of Dragonblight, the first things you see in the background when arriving through Mo'aki Harbor or basically any other entry point to the zone. This article is about the questchains of the temple, therefore it contains heavy spoilers.
This is where the dragon aspects and their ambassadors meet to discuss dragon business. Now it's full of Wyrmrest Accord NPCs who are united to solve the Malygos problem. The faction is lead by Alexstrasza, the Lifebringer herself. She can be found in the top chamber and after some long questlines, players eventually earn the right to talk to dragonqueen. Middle floor has only one humanform dragon, Lord Afrasastrasz, charged with defending the temple from the continous blue dragon attacks. Base floor has general NPCs, a magnataur questlady, basement has lots of titan waygates.
Next to Alexstrasza there is Krasus, consort of the dragonqueen; then there's Chromie (from Western Plaguelands) ambassador of the Bronze Dragonflight; Lord Itharius, ambassador of the Green Dragonflight and Nalice, Ambassador of the Black Dragonflight. They all give quests, more than interesting ones at that.
