Where can I find Gunmar in the Dawnguard quest "A New Order?"

Question

In the Dawnguard quest A New Order, Sorine had a quest marker but Gunmar does not; I can't find him. How can I get access to the Vale and get Auriel's Bow without doing the quest? Could someone give me an idea as to where I can find him?

I'm playing Skyrim - Legendary Edition on the Xbox 360.

Answer 1

As you're playing the Legendary Edition you have all of the DLC, including Dragonborn. As such, you should be able to find Gunmar in one of the following locations:

In the Skyrim overworld:

• Fallowstone Cave
• Brood Cavern
• Crystaldrift Cave
• Bonechill Passage
• Clearspring Tarn
• Cronvangr Cave
• Honeystrand Cave
• Pinepeak Cavern

Or in the Solstheim overworld:

• Northshore Landing
• Horker Island

If you can't find a map marker for him in the Skyrim overworld, he's probably at one of the two locations in Solstheim.

Answer 2

I found him at Gyldenhul Barrow in Solstheim.
