I have just traveled to the Temple of Ruunwald after going through the excavation site. I can't get past a locked door because it says I need to have a key. I have scoured all over the circular room you first drop in to, looted the ornate chest, and have found no key. There are two pathways I can see that lead out, one leads to a locked door that leads to Skyrim. The other is the one I just mentioned, and I assume Floentius is on the other side.
Did I miss the key back in the ruins?
If I did I am essentually stuck here for all eternity. Help!
