Three urban locations tied to Paizo's Shattered Star — a brothel turned slaughterhouse, a derelict noble villa, and a sewer-bound shrine. They share a city's underbelly mood and slot together as a chain of grim stops as the party works a case through the streets and the dark below them.

The Scarlet Fog is a two-story pleasure house, its ground floor a warren of curtained bedchambers around a tiled bath and a barrel-lined common room — bodies sprawled across the floor where something went very wrong. Upstairs holds more private rooms. The tight, partitioned layout suits a tense search or a room-to-room fight.

Kaijitsu Villa is an abandoned manor on overgrown grounds, its rooms cluttered with smashed furniture and debris around a faint ritual circle, with a detached outbuilding nearby and a tiled-roof residence below. The wreckage and broken sightlines make it ideal for an eerie investigation or an ambush among the ruin.

Sewer Temple hides a tiled shrine at the end of grimy sewer channels — brick tunnels of murky sludge open into a clean flagstone complex with a storeroom of crates and barrels, a dark pool, and a boat alcove. The contrast of filth and hidden sanctuary suits a covert approach toward a secret rite below the city.
