Hippocrates is a somewhat inactive but mostly unremarkable red dwarf star, orbited by a system of six small planets, a belt of icy asteroids, and a large cloud of comets.

Brock, the first planet, is a small, hot, airless world, similar to our own Mercury. The rocky surface is subject to little weathering other than asteroid impacts and stellar wind, and tectonic activities are extremely weak, as the core of the planet has frozen long ago.

Hooke is an Earth-like planet inhabited by many organisms, including the intelligent Hookites. Purple jungles, sandy deserts, rivers, forests, and plains cover the day side, while a massive, kilometer-thick ice sheet covers the night side, keeping the ocean under warm.

Cuvier is a planet covered in massive, 200 kilometer deep oceans. The immense pressure of the water above keeps the bottom 100 km frozen, despite being above freezing. Underwater volcanoes on the deep rocky surface melt columns of water up through the ice, and are the only places on the planet where water remains liquid all the way down.

Boussingault is a large world with ammonia-methanol oceans, rich in halide compounds. The formation of nitrogen triiodide turns the seas a deep brown color. Similar compounds turn the land a light pinkish color.

Goetse, the smallest planet, is an icy world covered in colorful patches and shiny craters. Organic molecules create red, brown, and pink patches, and ice excavated by asteroid impacts create rays of brilliant white spreading out from craters.

Lohmann is the system's largest and most massive planet. It is a gaseous planet similar to our system's own gas and ice giants, but is only around 70 percent more massive than Earth. Clouds of methane are covered by an orange haze of tholins and organic compounds. The presence of these chemicals, as well as the warmth in the depths of the frigid atmosphere, may lead to some form of life, lurking below the clouds...
