More Components of Importance

During the quest chain to upgrade the Dungeon Set 1 Helm and Chestpiece to Dungeon Set 2, adventurers will have to complete a quest called More Components of Importance. This quest could be one of four quests:

**Follow up Quest:The Right Piece of Lord Valthalak's Amulet (Stratholme).

**Follow up Quest:The Right Piece of Lord Valthalak's Amulet (Lower Blackrock Spire).
*Frostwhisper Gorge - Acquire a Starbreeze Village Relic from Frostwhisper Gorge and return it to Bodley inside Blackrock Mountain.
**Follow up Quest:The Right Piece of Lord Valthalak's Amulet (Dire Maul).

==Addendum==
The matrix for which first component quest and the successor quest is at least incorrect for my experience, as of patch 1.12.1. My first Components of Importance was for Purgation Isle, but my second was for Tyr's Hand.
Note 2: Here too, I've got my first Components of Importance as Hive'Regal, but my second was Frostwhisper Gorge.
Note 3: As of patch 2.0.12, my first Components of Importance was for Purgation Isle, but my second was also for Tyr's Hand.
Note 4: As of patch 2.4, my first Components of Importance was for Purgation Isle, and my second was for Hive'Regal. (Seems to be a random pairing each time)
