An End to the Killing

If you can't see Anduin in the Throne room. You might be phased for stormwind for 5 or more other questlines. If you started any questline that is phasing Stormwind, you need to complete it first, to bring you back into the correct phasing.

"On Whispered Winds" - Darkshore BattleFront Quest Line

Check if you got the quest line On Whispered Winds
You need to continue the quest line until you complete "Shores of Fate"

Macro to check: If any of these show "false", click the link above for "One Whispered Winds" and complete them. Stormwind should be back to normal afterwards.

/script for q,i in pairs({["On Whispered Winds ="]=53847,["Waning Hope ="]=53849,["Shores of Fate ="]=53988})do print(q,IsQuestFlaggedCompleted(i))end

"The Hand of Fate" Questline.

Check if you got the questline or any of the followups from The Hand of Fate

Macro to check: If any of these show "false", click the link above for "Hand of Fate" and complete them. Stormwind should be back to normal afterwards.

/script for q,i in pairs({["The Hand of Fate (1) ="]=47221,["The Hand of Fate (2)="]=48506,["Two If By Sea ="]=47222,["Light's Exodus ="]=47223,["The Vindicaar ="]=47224})do print(q,IsQuestFlaggedCompleted(i))end

"The Legion Returns" Questline

If you did not complete the initial Legionquestline, then Anduin is not king for you yet and thus you won't find him in the trone room. Check this questline: Legion: The Legion Returns

Macro to check: If any of these show "false", click the link above for "The Legion Returns" and complete them. Stormwind should be back to normal afterwards.

/script for q,i in pairs({["The Legion Returns ="]=40519,["To be prepared="]=42782,["The Battle for Broken Shore ="]=42740 ,["The Fallen Lion ="]=40517})do print(q,IsQuestFlaggedCompleted(i))end

"Sizing Up The Opposition" Questline

You can't be on Sizing Up The Opposition either, this will phase stormwind as well: /run print(IsQuestFlaggedCompleted(47473))

"A found Memento" Questline

You can't be on A Found Memento or the questline Summons to the Keep either, this will phase stormwind as well:

Macro first quest: /run print(IsQuestFlaggedCompleted(46268))

Macro questline: /script for q,i in pairs({["Summons to the Keep ="]=46272,["Consoling the King="]=46274,["A Kingdom's Heart ="]=46275,["The King's Path ="]=46282})do print(q,IsQuestFlaggedCompleted(i))end

Good luck

For those that were a little stuck on this quest like I was, I wanted to shed a little light. The part where it tells you to talk to the NPC to have him blow up the ship can be a little confusing seeing as he is following you around and unable to be interacted with.

What you have to do is go to the very top of the ship, where you will find a void portal. Take the void portal and once you are on the mainland, the NPC will allow you to talk to him and you will have the option to blow up the ship. Once you select that, there will be a small cutscene and the quest will complete.

I hope this helps :3

What nobody mentioned, and took me quite a while to find out is that - you need to have REVERED reputation, in order to proceed with this step.
