Hrognum

Hrognum is a fictional planet within the Andromeda Galaxy, first introduced in the science fiction novel "Chronicles of Xylos." The planet is characterized by its unique dual-sun system, resulting in extreme diurnal temperature variations. Its surface is predominantly covered by crystalline deserts interspersed with shallow, saline seas. The atmosphere is thin and rich in nitrogen, with trace amounts of argon and methane, making it largely uninhabitable for carbon-based lifeforms without specialized suits.

The indigenous flora of Hrognum are silicon-based, adapting to the harsh environment by forming intricate, slow-growing crystalline structures. Fauna is sparse and primarily consists of subterranean, bioluminescent organisms that feed on geothermal energy. The dominant sentient species, the K'tharr, are a silicon-based lifeform possessing a communal consciousness. They communicate through complex vibrational patterns and light emissions. The K'tharr civilization is ancient and technologically advanced, though their focus is on internal planetary development and energy manipulation rather than interstellar expansion. Their societal structure is matriarchal and deeply integrated with the planet's geological processes. The K'tharr are known for their stoic nature and profound understanding of energy transference.
