The "mad scientist" is probably the astrologer. You could ask him about your future...
But if you are there, then you are from where you wanted to go...
Well, I just took out my map - and I will try to explain the way. But I can't guarante to make more sense than Alichica. :lol
Well: go straight North form the Gate Plaza till you reach Fountain Plaza. Turn left (that street should be called Naufara Darb but I don't remember what it translates as. It is certainly not Sultan Darb!!!)
You will then reach a "crossroads" (where you only have the choice to go right or left). Go right.
Follow the street till the next crossroads. Go left.
Follow the street till the next crossroads. Go left.
Follow the street to the end and you should be there.
Good luck. Hope that helps
