As you all cross the bridge and begin to head back towards the cart in the middle of the town square, you notice something rather unusual.  It seems that a large number of horsemen have arrived from somewhere and partially encircled the cart.  Though you are a bit far away and unable to discern too much until you get closer, it seems as though one of the riders has taken the lead and approached the caravan guards you left behind.  At the moment things seem to be going peacefully enough, but there is no mistaking that these riders are all armed and likely ready for a fight if some manner of hostile action were to provoke them.
