Well its quite simple actually all you have to do is make any character but make sure his security is one of his major skils then around like level 19-22ish you can go to vivec (make sure to bring at least 5 lockpicks of each type if you have them)and near the vivec temple go to the top of the stairs and you'll see a door with the lock 100 (with my character i was able to open this door with a journymans lockpick but just to be safe and fast id advise you to use a secret masters lockpick, you can get these from Hercerindes in Balmora after you finish Habasi,s theives guild missions). Now i'm giving a little spoiler to those who just can't seem to crack the lock inside the door is Lord Vivec(of course) but the real amazing thing inside is not only Vivec himself but there in the back of the room is about 5 sheets of paper (i'd advise that if you have sticky hands not to steal these this could be abig factor later on in the game ) on these sheets of paper is the imperial leigons plans to over-throw Dagoth-Ur step-by-step preety cool huh. Heres a challenge to those that need a little more of a challenge, write down whats on these papers and then execute the plan to over throw Dagoth-Ur on your own HEHEHE.(i've got like half-way through it but there werent enough blight cure potions to help me out through the rest of the plan, mabye you'll have better luck than I. I wish you all well if you do).
