I was travelling towards a village, and I came across a cave titled "Geirmund's Hall," which turned out to be a Nordic ruin. After some exploring, I've come across a room full of Draugr. I dealt with them, and killed one Draugr Wight on an island high above the floor with my bow. I took the staircase up, slew a Draugr Scourge, which left me on an open cliff, an draw bridge rising up from the island I shot the Wight on, and a lever. I pull the lever - which resulted in me being impaled in spikes. The draw bridge will not come down. Has anyone come into this ruin, and knows how to do this? I've been stuck here for a half hour and some help would be greatly appreciated. I'll give you pleasure long time.
