So first of all i love the DLC and i have been having loads of fun but i just completed the Soul Cairn quest, So i got both the scrolls and i talked to the dragon got his thu'um( beat him too ) and talked to the mother and walked out of the soul place i talk to the girl who follows me and we chat a bit about a bow and how me might have to kill her dad aaaand then nothing happens, No way point it does seem t say to talk to the moth priest but it isnt telling me where to go.

any help?

Edit: i chose vampire path and i went to where the moth priest is in fort dawnguard and he isnt there either.

Which quest are you currently on? To determine this, look in your journal and make note of the quest name and your current objective. I'm assuming that you currently have both the sun and blood scrolls. You probably still need to find the dragon scroll. See http://www.uesp.net/wiki/Skyrim:Discerning_the_Transmundane.

The moth priest (Dexion) should not be in Fort Dawnguard (if you have chosen the vampire path), he should be in the Castle Volkihar keep. It has been reported that sometimes you may find Dexion chained to a wall in Castle Volkihar.

Seeking disclosure

It says this

"Vampire: I've secured both of the Elder Scrolls needed to fully decipher the Tyranny of the Sun and pinpoint Auriel's Bow. I need to return to Castle Volkihar where Dexion is imprisoned so he can begin his reading. "

But i see no way point or anything , Where is he located? maybe i can just find him and try it.

Thanks for the help, i found him ^^! now i can beat it before i start my new job o3o
