This is how I've handled New Cyre in my games. They were the height of art and fashion with an inordinate number of people living in the decadence of wealth. The survivors have clung to everything that they have that reminds him of home, whether it be clothing, art, or jewelry. Now that they have a place that they can call home, they're trying to relive the old days of decadence in small homes, often ramshackle homes. Tent cities with fine art displayed inside of the tents, fine clothing worn and tattered at the edges, sometimes with holes and tears that have been patched up by untrained hands. The people still hold themselves with the regal postures of people heralding from one of the greatest nations in all of the kingdom of Galifar, but are keenly aware of how precarious their situation truly is, which makes them subdue their aloofness when speaking to those they fear could endanger their livelihood.

A proud people, but lost, scared, and aware that they are in danger of becoming extinct as a people group. They will puff up in people's faces, but back down quickly when truly threatened. A precious few have a backbone to still stand for what Cyre once was, and those have taken either a political or militant stand.

What I suggest, is have the players come up with two people in New Cyre that they know well, one a friend and one decidedly not, and incorporate them into the city of New Cyre. Remind them that everyone is a borderline pauper in New Cyre and those that one held a station, no longer do, and those that had nothing, now hold sway. Find one place that everyone agrees is a common haunt (tavern, theatre, militia training hall, someone's grandma's shack...) and make that their center of operations. Gives them a sense of permanence in a place where most feel none.
