Well im doing the dawnguard vampire part. Specificaly, im on "Chasing Echoes", and within that im on the fourth checkpoint "Explore Castle Volkhars Ruined Tower"

I have gone through the entire thing, and Im stuck at what I presume is the very end because literally, and I kid you not, Serena says "Were getting close, im sure of it" every exactly 2 seconds. There has to be a lever or a something to pull or push to get past this wall but I have searched everywhere and do not see it. I have searched a while now. Glitch maybe? Heres a picture of where I am located (no spoilers)

The wall to the left has two candle holders, activate the one on the left side.

Thank the heavens, you have saved me more countless hours of searching.
