Can't Start The Hand of Fate

Before you can start The Hand of Fate (Alliance/Horde) and journey to Argus, you must be level 45 and complete the following patch content milestones on at least one of your characters:

• Uniting the Isles
• Armies of Legionfall
• Assault on Broken Shore

If one of your characters has completed the Broken Shore scenario and your alts still aren't offered The Hand of Fate:

1. Log in to the character that completed the scenario and log out.
2. Log back in to your alt.
3. Talk to Khadgar at Krasus' Landing and accept the Assault on Broken Shore quest.
4. Speak to Khadgar again and choose the option skip the scenario, then complete the quest.
5. Come back to Dalaran to pick up The Hand of Fate.
