SinfulDeath

What you have to do[and beleive me on this] is go swim in the water and drown in it. Remember "breathe the waters of his glory" something or other?well that basically means go jump in the water and drown. After that the screen goes black and when you look up out of the water theres a pathway extending out over the water to the barrier. Now all you have to do is hand the silver sword to the dremora and your set.
