The Arrowcave is the headquarters for Oliver Queen and his team. It houses Oliver's equipment and costume for his heroic persona, Green Arrow, formerly The Arrow. The base now also holds the gear for the Black Canary, Speedy, Spartan, and for a brief period the White Canary too. It also has Overwatch's tech setup. Used by Oliver Queen, John Diggle, Felicity Smoak, Thea Queen, and Laurel Lance, it is sometimes referred to as The Foundry, The Lair, or The Bunker.
