Getting into the Thieves Guild

Talk to any ordinary citizen in Cyrodiil (though sticking to one in the Imperial City is wisest) after looking at a Gray Fox poster, and they'll tell you that the beggars are the eyes and ears of the Gray Fox. Then, go find a beggar and use speechcraft to get their disposition over 70. Say you want to work with the Gray Fox.

The meeting place is the Garden of Dareloth. It's this location on the waterfront:



Wait until midnight, and Armand Christophe (guy with a torch in one hand you can't miss him!) will show up. You should get his disposition at 70+ before talking to him.

There'll be a quest between three others and you to join the guild. The task is to steal the diary of Amantius Allectus, and you can talk to a beggar (expect to raise disposition to 70+ and to pay gold, too) and get an exact location if you like.

Go to the Temple District, and go to this point:



When you break into the house, turn right and look for a chair and a desk underneath a tapestry that's hung on the wall. The desk has the diary. If it's not there (it should be if you move quickly enough), the fellow thief, Methredhel, got to it first. Go back to the waterfront.

Her house is right next to the abandoned shack, which is in front of the Garden of Dareloth.

I broke in at about 10:50, so early-morning seems to be a good time to go in. When I went in there were only two people there and they were both asleep. To your immediate left when you go into the one-room house is Methredhel's chest, which'll have the diary. Pick the lock (be sure everyone's asleep, of course, so you don't get caught) and take the diary.

Now you just wait in the Garden until midnight rolls around again, and turn the diary in. Congratulations, you're now in the Thieves Guild!
