The Fourfold Sequence

You enter a circular temple chamber where the air shifts through four impossible climates. Blue sparks crawl across one brass basin, red light pulses beneath another, gray dust gathers around a third, and cool mist spills from the last. A sealed stone door fills the far wall, its four rings etched with elemental glyphs. Silver channels connect the basins like veins, and faint lines of light move through them in a repeating pattern. The room smells of rain, ash, wet stone, and charged metal.
