I am having a heck of a time getting the Chorrol oblivion gate closed. I have opened all of the gates, gone through each tower, and worked through the entire map that I can see both inside and outside of the citidels. Can someone post the specific path one is supposed to take? It's got to be something small I am missing at this point.

Scroll a little down and you will find Chorrol...

I'd already found and gone through the Chorrol gate. It's getting to the Sigil stone to close it that I am having a problem with. I've gotten to the main central tower, but all the paths I've found seem to lead to dead ends or back on themselves.

Hmm... Well I don't remember the router but you should be able to find it, just have to search

done it yesterday. Open all the gates alright. From one of these gate-control towers (i don't know which of them though) you get to the main towers second floor or something. From there proceed like in every other gate.
