The City Barracks Harmonium Headquarters. Over three hundred feet to a side but only sixty feet high, the Barracks looks like a slab of stone that's taken on a militant bent. Its lone entrance is manned by four heavily armored guards, and for blocks around, the faction's patrols keep the streets orderly and quiet.
The Singing Fountain Landmark/Public Interest Site. Atmosphere: A circular stone pool, fully 100 feet across, at the center of which is an enormous water basin on a great stone pedestal. Dozens of metal basins beneath catch the water spilling over from above, giving off dulcet, hypnotic tones like voices, wind instruments, and bowed strings engaged in perfect melody. The upper basin is a common roost for the gray-green pigeons of the ward, and the otherwise pure water of the fountain often sports their discarded feathers. Keeper: Though not officially its owner, Black Marian, a Godsman and priestess of Bragi, watches over the fountain and uses it to make her livelihood. A vocalist and prophetess, Marian (a pale, flaxen-haired human who earns her epithet from her ebony-black eyes) cleans out the fountain whenever it should be clogged with litter or pigeon feathers. At random hours, she acts not only as a public entertainer, singing along with the music of the basins, but also as a diviner, interpreting a body's future for a small donation.
The City Courthouse Fraternity of Order Headquarters. Surrounded by establishments catering to judges, advocates, and anyone awaiting court appearances, the Court is constantly abuzz. Freelance legal scholars acting as attorneys and advocates swarm the promenade at all hours, distributing handbills and shouting out their fees.
The Prison Mercykiller Headquarters. The Prison stands at almost 200 feet (though the last fifty or so are the long, tapered rooftops and thorny gables of the guard towers). Roughly a quarter mile to a side and rumored to have chambers hundreds (or thousands) of feet underground, the place's sheer capacity for both prisoners and their jailers and executioners is staggering.
The Armory Doomguard Headquarters. Over four hundred feet high and covered in razorvine, the Armory lacks all subtlety. Foot traffic is constant, as entrants buy and sell weapons from all over the planes.
