Kalystria

Kalystria is a fictional planet within the Andromeda Galaxy, notable for its unique ecological system and the ruins of an ancient civilization. The planet is characterized by a dense, bioluminescent jungle that covers most of its surface, illuminated by the planet's twin moons. The flora of Kalystria exhibits unusual properties, including symbiotic relationships with microscopic organisms that produce light and energy. Fauna ranges from small, insectoid creatures to large, reptilian predators adapted to the low-light conditions.

Archaeological evidence suggests that Kalystria was once home to an advanced civilization, referred to as the "Luminians" by xeno-archaeologists. Their cities, now overgrown by the jungle, are constructed from a crystalline material that still retains some residual energy. The Luminians appear to have vanished abruptly, leaving behind complex artifacts and intricate celestial maps. The cause of their disappearance remains a subject of ongoing research and speculation.

The planet's atmosphere is breathable for most carbon-based lifeforms, though it contains trace amounts of a mild hallucinogen, which some explorers report to have experienced. The climate is generally warm and humid, with frequent rainfall. Kalystria's gravitational pull is approximately 0.9 standard G. Due to its remote location and the hazardous nature of its jungle, Kalystria is primarily visited by scientific expeditions and independent artifact hunters. Resource extraction has been minimal, largely due to the ethical concerns surrounding the Luminians' legacy and the ecological fragility of the planet.
