I am on a quest where I must retrieve a sword from the ruins of Mzinchaleft. Well, it's been a long (waaaay too long) and perilous journey, but I finally found the sword and everything will be worth the trouble because of all the loot....but I can't get to it because of this thingy:
Obviously, I missed something but I have no idea what it is. There is a room full of loot that's off-limits until I can figure this thing out! How do I activate this?
