Found in the northwestern corner of Barsaive, Iopos is ruled by Uhl Denairsatas, a powerful and ancient human magician. The Denairastas clan have been revealed as an enemy of Throal; they were responsible for the death of King Varulus III, and no doubt have had their hand in even more plots and plans. they have agents in every city, many of them related to Uhl, all of them highly skilled adepts and magicians. The clan patriarch enjoys pitting them against each other, and they often have their own internal struggles to prove themselves worthy heirs.
The city is a clean, order place, but it is not very welcoming to visitors—informants are everywhere, and there is little that happens in the city that does not quickly find its way into Uhl's information network. With the Therans currently out of the picture, the Denairastas are arguably the greatest threat to the freedom of Barsaive's people.
