The Jagged Crown (Stormcloak)

Walkthrough
Having decided to help the Stormcloaks in the Civil War, the ugliness of war rears its head. It has come to Galmar Stone-Fist's attention where the fabled Jagged Crown can be found. This crown was worn by the High Kings of old, and thus it would be a powerful symbol for Ulfric Stormcloak's ambitions towards that office. Galmar makes it a priority to retrieve the crown, though he does expect resistance by the Empire, since their spies are aware of the situation.

Talk to Galmar
Return to Palace of the Kings and talk to Galmar Stone-Fist, he mentions that the first mission will be to take on the Empire at Korvanjund and retrieve the Jagged Crown.

Last chance to join the Imperials

Talk to Galmar

 * Dragonborn:
 * What's the mission?


 * Galmar:
 * I've found the resting place of the Jagged Crown. Can you believe it? Will, I'm almost certain.
 * We're headed to Korvanjund. But, if old King Borgas is indeed buried there, we're bound to run into trouble of some kind.
 * Your fellow Stormcloaks are already assembling outside the tomb. I'll meet you there as soon as I'm finished up here.

Meet Galmar outside Korvanjund

 * Galmar:
 * What's the Legion doing here? Damn Imperial spies... Well, should be fun for us, at least. They don't seem to know we're here yet.
 * Ready to spill some Imperial blood for Skyrim?


 * Dragonborn:
 * I'm ready. Let's go get them.


 * Galmar:
 * That's what I like to hear.

Deliver the crown to Ulfric Stormcloak

 * Dragonborn:
 * Here's the Jagged Crown. I believe you owe Galmar a drink?


 * Jarl Ulfric Stormcloak:
 * Damn him - the old bear was right! Did you run into any trouble?


 * Dragonborn:
 * The Imperials were there ahead of us.


 * Jarl Ulfric Stormcloak:
 * Damn it. What were they doing there? Imperial spies are everywhere. Never forget that... I trust you gave them a thrashing? Now then...

Get new orders

Glitch with the Jagged Crown
