anyone know where yardis is for this quest?

Ok. You talk to Carolines friend. Then you talk to Caroline which is in the theatre. Then you go to yardis which is... In the city top left part of the map I believe, or if not then he's out by the docks. Near the boat guy the ship boss that's it. Then he tells you to go talk to caroline again then you gotta go to the doctor in the town straight across from athens I forgot what it's called then you go give it to him it has no effect then you get him a cutless and bash him over the head and boom you major exp/money
