-Turn off AI and just run from the guards. Don't fight them, there's no point. At the Flaming Fist Barracks, don't worry about killing anybody. If you do you won't lose rep. From there just go up to where you met Duke Eltan before. You'll find a guy who claims to be the Duke's healer. He's actually a Greater Doppelganger. Kill him, talk to the Duke and carry him to the Harbor master's place in the port section of the city (south central). It's the biggest building on the map. Also, if you talked to Tamoko, you should have heard of some people in the Undercellar Stylthie and I forgot the name of the other person. You should go there and kill them, just don't hurt any of the Courtesans or you lose rep. You should be able to figure out where to go from there. Hope this helps!
