Nаrcissus is the leаder оf аn early settlement (where we might lоcate mоdern-day Italy). He has access to skilled workers and technical experts that provide a competitive edge in trade, technology, and the readying of a modern military.  He has amassed a sizeable army that can not only defend his territory, but can plunder and subjugate nearby regions so that enough peasants and slaves are available to feed the ever-expanding classes that are removed from agricultural labor (rulers, priests, administrators and bureaucrats, etc.). In fact, a new masonry class recently completed a 60-foot wall around the city. Narcissus is increasingly concerned by the expansion in size and capabilities of neighboring settlements. He realizes that just as he learned to control the natural environment enough to build food surpluses and extend his control over women, peasants (via taxes) and slaves, other rulers have learned the same lessons. Now, his biggest obstacle to maintaining power is not withstanding security threats posed by weather, natural disasters, or plagues, but is instead the danger posed by those who rule other settlements.
