You are on Sessius Avenue.  This long cobblestone street extends north a
little bit more.  In the near distance the castle seems to get bigger and
bigger as you approach.  You realize it is much larger than you expected. 
The merchants line the sides of the streets with small shops in which they
can sell their goods, and more importantly, make a profit.  In the horizon
Mount Vesuvius comes into view, looking even more dangerous as you get a
little closer.
