The greatest ballroom in the Imperial palace has been pressed into this event; it's not quite fair to say that it's more of an arena with a dance floor, because you can't quite fit that inside a realistic palace, but the design of it takes something from an arena. There's three levels to the surrounding structure, from which you could look down on the dance floor and the platform that identifies the room's head, balconies and boxes with one-way windows that look outward, reachable by a confusing and deniable maze of halls and stairs. Whoso made this room recognized and intended that at least half the people in it were going to sneak off and conspire together, and half of those wouldn't want to be identifiable as having left or returned in each other's company.
Today only the room's center has been left clear for dancing, the rest of the room occupied with some of the most impressive exhibits of the Nidal war. The spiked head of a Phylacator, a profoundly dangerous kyton that required every 8th-circle of Cheliax plus Gorthoklek to slay without any casualties among important people. A handkerchief carefully soiled with the blood of a Black Triune now fled. A beautiful and muscular shackleborn tiefling male, once second-in-command of a brigade, now with his fingers cut off, chained with spiked chains piercing his skin, for sale to the highest bidder this night.
Most of Nidal's most portable and value-dense treasures, precious metals and gemstones and magic items and scrolls, are long since Teleported out of the country by rats fleeing their sinking ship; but somebody managed to leave behind a Helm of Brilliance, meant perhaps for internal defense against Kuthite rebels. It is exhibited here, lying proof that immediate wealth was gained of Nidal and not just an eventual tax base.
