Solulla

Solulla is a fictional planet located in the Cygnus X-1 system, as depicted in the science fiction novel "The Last Star" by A.R. Sterling. The planet is described as having a predominantly arid climate with vast, sandy deserts and sparse, hardy vegetation adapted to extreme conditions. Its atmosphere is thin and tinged with a reddish hue due to high concentrations of iron oxide dust.

The surface of Solulla is characterized by towering rock formations sculpted by relentless wind erosion. Deep canyons and ancient, dried-up riverbeds hint at a wetter past. The planet orbits a binary star system, causing dramatic shifts in light and temperature throughout its cycles. Due to the harsh environment, life on Solulla is presumed to be scarce, likely consisting of extremophile organisms or highly specialized flora and fauna.

According to the narrative, Solulla was once home to an advanced civilization that disappeared millennia ago, leaving behind enigmatic ruins and technological remnants. These ruins are often found buried beneath the sands or nestled within remote geological formations. Explorers and archaeologists are drawn to Solulla in hopes of uncovering the secrets of this lost civilization and understanding the planet's geological and atmospheric evolution. The planet's name itself is believed to be derived from a word in the ancient inhabitants' language, possibly referring to "sun" or "dust."
