Once the largest city in Unther when it was a major port on the naval trade route, Messemprar shrank when merchant vessels began to avoid Unther's coast and Gilgeam's excessive trade taxes. A brief civil war within the city broke out a few years ago after a tax revolt that led to a food riot. The riot ended when the wizards of a secretly anti-Gilgeam group called the Northern Wizards took control of the city.
Now Messemprar has more than doubled in size as refugees from other cities in Unther flood into it. The Northern Wizards wished to be free of Gilgeam, but did not expect their freedom to be followed by the swords of Mulhorand. They have been working frantically to fortify their city against the army and pleading with the pharaoh for a cessation of hostilities. The Northern Wizards have a standing agreement with several adventuring groups to smuggle food into the city.
If anyone could be said to be the leader of unconquercd Unther at the moment, it might be Isimud (NG male human Wiz15/Dev3 of Mystra), who is the foremost of the mages of Messemprar. His fellow mages are a fractious group whose power is not well respected by the turncoat nobles of their host city.
