Much as the plane of Carceri itself, Curst is little more than a massive prison, though in the case of this city it serves as a prison of the mind far more than a prison of the body. Here, exiles and refugees from across the multiverse congregate, nurturing their grudges and forging plans to some day take revenge on those that did them wrong — a day that for most tends to move further and further into the future the longer they remain within the city walls. Most of the people of Curst keep themselves locked into these old wrongs against them, focused on the glory of vengeance that few of their number will ever achieve.

The area immediately around the city is dry and dusty, with neither plant nor animal life of note but for the thick fields of razorvine kept clear from the roads only by the devoted efforts of the upper class (or more precisely, their servants), eager not to let themselves be cut off from their few connections to the rest of the planes. Still, travel to the city is far from safe, the vines along the roads studded with the bodies of those not careful in their step. Thanks to the danger and the lack of attraction in the city — Carceri never being a popular destination for either merchants or planewalkers — the roads about Carceri are rough and empty, with the sight of other passersby quite rare.

The town is near Semuanya's Bog, where the Party fought the Black Dragon (24). The Party also escaped to a gate in Curst from Zelatar (after Skippy recalibrated the gate) (27)
