Ikkunia

Ikkunia is a fictional exoplanet used in science fiction and world-building exercises. The term has appeared in novels, role-playing game supplements, and online guides as a concrete example of an ocean world. It is not associated with any confirmed astronomical observation.

In common depictions, Ikkunia orbits a sun-like star and features a predominantly ocean-covered surface with scattered archipelagos. The planet is frequently described as having strong ocean currents, shallow continental shelves, and a relatively thick atmosphere that supports stable climates and cloud systems. In some canons, a ring system or a faint magnetosphere is noted. The diversity of climates is usually explained by latitude bands and ocean heat transport, creating temperate regions near the poles and more dynamic zones around the equator.

Life and culture: Some works posit microbial life in the oceans, while others introduce adapted or sentient species. In several guides, ruins or megastructures hint at ancient civilizations that once exploited the planet's oceans. The setting is commonly used to explore themes of planetary habitability, terraforming challenges, and the ethics of ecological alteration.
