Triglav

Hydri
 * Hydri is a terrestrial planet only known from scan data picked up by unmanned probes. Temperatures in Hydri's orbit are dangerously high.

Alyosha Lacertae Russki
 * Hyrdri is not a terribly interesting world. It has a thin atmosphere of nitrogen and methane, and the scorching surface is mainly composed of alumina with deposits of platinum. The world is tidally locked to Triglav, leaving the sunward side a scorched and irradiated wasteland, and the dark side frigid and ice-crusted.
 * Alyosha is a terrestrial world with a thin atmosphere of carbon dioxide and argon. The surface is scorching hot, primarily composed of iron with deposits of nickel. Like Hydri, Alyosha is tide-locked to the blue giant, forever "looking into the face of the Triglav."
 * Lacertae is a typical hydrogen-helium gas giant with traces of methane and sodium in its atmosphere. The heat of the star Triglav is slowly blasting away the gas giant's massive atmosphere, which is visible as a long, dim tail that trails behind the planet.
 * A standard hydrogen-helium gas giant, the methane in Russki’s atmosphere gives it an azure hue.

Lahmu Branda
 * Russki is too small to be a "standard hydrogen-helium gas giant". It is too hot to attract ices. It is more likely a superterrestrial protoplanet. The clear gasses in its atmosphere will suffice to induce a Rayleigh scattering effect and an appearance of deep blue (with clouds).
 * Lahmu is a huge gas giant, with an atmosphere tainted by methane and chlorine.
 * Branda is a small terrestrial world with a thin atmosphere of krypton and xenon. Its frozen surface is mainly composed of carbonaceous material, water ice, and low-density silicates. Rare but concentrated lodes of light metals have been deposited by asteroid impacts.
