Trials of the Archons

Raid flagging
All quests are located in Amrath. Suniro bestows War of the Archons chain. You'll be flagged for the raid after completing the chain (even if you do that on heroic).

Chain reward is random loot (heroic has a chance to drop Collapsed Portable Hole though).

The Celestial Alliance is the name of the story arc where the storyline involves a classic DnD artifact.
