An Alliance character is required to loot the bonnet, but Horde can transmog into it once acquired.

Briefly leave and return to the house, and on the 2nd floor you can loot the Bonnet.

Head to Eastvale Logging Camp and give the locket to Alaina Hearthsong inside a house at 85.5, 69.7.

Complete the Broken Shore scenario and The Battle for Broken Shore.

Pick up Charred Locket from the Ashes of a Fallen Crusader, located on an altar.

There is a fourth hidden item requiring Stage 6, 7, or 8 of the Broken Shore for Alliance: Alaina's Bonnet

Lenny 'Fingers' McCoy at Stormwind Harbor sells Lucky Shirt and the flavor items Old Lucky Coin, Lucky Rat's Tooth, and Lucky Charm.

Ravika by Bladefury's Dock sells highly sought-after items from Patch 5.3: the cosmetic item Griftah's Authentic Troll Shoes and toys Whole-Body Shrinka', Sen'jin Spirit Drum, and Xan'tish's Flute.

Fo'rum the Postmaker by the Draonsh'ar Blockade sells Angry Post, Happy Post.

As Demon Hunters cannot complete the Broken Shore, they can never see these NPCs. You must be level 98+ and on the Broken Shore questline, before boarding the boat in Battle for the Broken Shore to see these NPCs.

The following NPCs are only accessible before the Broken Shore event is completed. Fresh characters that did not complete Broken Shore must go through the scenario when Legion hits. If you completed this before August 30th, you can skip the Broken Shore scenario on that specific character, and instead start with In the Blink of an Eye to teleport to Dalaran. It can only be completed once per character.

Spoilers within! This is available to all level 98+ players except for Demon Hunters. The Alliance and Horde both investigate the Broken Shore with their faction leaders. Before you can quest through the Broken Isles, you first need to run through the Broken Shore (or Mardum if a Demon Hunter), witness Dalaran moving to the Broken Isles, acquire your Artifact Weapon, and unlock your Class Hall.
