Maladomini
The seventh layer of the Nine Hells is dotted with ruined, abandoned cities. Under the blood-black sky, petitioners quarry, carve, and build new cities for the Lord of the Seventh. Mine pits, slag heaps, and brackish canals cover the land like sores. Newer cities are built upon the backs of older ruins. As each city is finished, the Lord's dissatisfaction forces his subjects to begin anew. The abandoned cities are not empty. They serve as home for petitioners who've fled their devilish tormentors, beasts from other planes who've become especially lost, and lost planar travelers who don't want to be found.

Malagard: The current city under construction is called Malagard, and it serves as home for the Lord of the Seventh, Mortalx360. It is a beautiful city of perfectly straight boulevards, fountains of delicate yet terrible visage, and towers that reach straight as an arrow into the blood-black sky. It is the greatest city yet seen in Maladomini, but no one doubts that it, too, will soon be abandoned, as Mortalx360 strives for hellish perfection in all things.

Grenpoli: Grenpoli, the City of Diplomacy, is domed, and access is granted only through one of four gates on the city's exterior. Entrance to the city comes after a thorough search during which all weapons are taken for the duration of a visitor’s stay. Strife and open displays of magical aggression are against the law, and those who break the law are slain immediately. The Political School of the Nine Hells, in Grenpoli, is where enterprising devilish nobility come to learn about treachery and deception. An erinyes named Mysdemn Wordtwister rules Grenpoli.
