Two distinct sites from Paizo's Shattered Star, each carrying a creeping otherworldly wrongness — places where the architecture itself feels like it belongs to something not quite sane, fit for the campaign's strangest, most cosmic-horror corners.

Embassy of Leng feels alien and cold — dark slate-blue stone chambers branching off a great central chamber choked with swirling white fog, walls erupting with jagged blue and pink crystals, with a flickering teal energy node and odd sealed rooms off to the sides. Run it as a disorienting set-piece: the fog kills sightlines, the crystal-lit junctions are the chokes, and the strangeness keeps players off-balance.

Temple of the Crawling Chaos is deep blood-red gloom — a dark maze of corridors and ritual chambers in oxblood stone, with a central pit of writhing fleshy matter, fish-headed reliefs and idols, cobwebbed crypts, and raw cave-mouths breaking in from the snow-pale rock outside. Run it as the cult's sanctum: tight maze corridors, the central pit as the dread heart, and the caves as a flanking back way in.
