Stillusk

Stillusk is a fictional planet featured in the science fiction novel "The Keplerian Gambit" by author Anya Sharma. The planet is depicted as a terraformed world located within the Kepler-186 system, known for its lush, alien flora and fauna. Stillusk orbits a red dwarf star, Kepler-186f, which casts a perpetual twilight over the planet's surface.

The novel describes Stillusk as a colony world established by humanity seeking refuge from a dying Earth. The colonists have adapted to the planet's unique environment, which includes a higher atmospheric pressure and a different gravitational pull than Earth. The native lifeforms on Stillusk are characterized by bioluminescent plants and large, slow-moving herbivores, adapted to the low-light conditions.

Stillusk serves as a central setting for the narrative, where the protagonist, Dr. Aris Thorne, uncovers a conspiracy threatening the colony's fragile existence. The planet's ecology and the challenges of survival on an alien world are integral to the plot, highlighting themes of adaptation, environmentalism, and humanity's place in the cosmos. The novel explores the ethical considerations of terraforming and interspecies relations through the lens of Stillusk.
