Key to the Arcatraz

The Key to the Arcatraz was used to access the Arcatraz instance in Tempest Keep.

While the key can no longer be earned, players can still ask A'dal for the key if they earned it in the past.

Source
The quest starts in Area 52 from Nether-Stalker Khay'ji. It's called Warp-Raider Nesaad, and it leads you on a series of soloable quests, ending with Full Triangle. After you complete this quest, you'll be asked to go to Shattrath and talk to A'dal, who will give you the quest to enter Arcatraz.
