Ennontrion is the capital of the Kingdom.  It is where the PCs will start.  In the city of Ennontrion the carrying of weapons is not permitted.  There are two exceptions to this:  the military/militia/royal guard, and the nobles.  Though it is not required, since Ennontrion is the capital of the kingdom, the laws of Ennontrion are followed by the other major cities, though this is not required and not always the case.
