Components of Importance

During the quest chain to upgrade the Dungeon Set 1 Helm and Chestpiece to Dungeon Set 2, adventurers could complete a quest called Components of Importance. This quest was one of four quests:
*Tyr's Hand - Retrieve a Brilliant Sword of Zealotry from Tyr's Hand and return it to Bodley inside Blackrock Mountain.
**Follow up The Left Piece of Lord Valthalak's Amulet (Stratholme).
*Purgation Isle - Obtain Soul Ashes of the Banished from Purgation Isle and return them to Bodley inside Blackrock Mountain.
**Follow up The Left Piece of Lord Valthalak's Amulet (Scholomance).
*Hive'Regal - Acquire Druidical Remains from Hive'Regal and return them to Bodley inside Blackrock Mountain. 
**Follow up The Left 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 The Left Piece of Lord Valthalak's Amulet (Dire Maul).
Which quest the player received did not seem to be based on class or race, but appeared to be random. They were all removed along with the classic Dungeon Sets with the release of Patch 4.0.3a.
