K2-18b is a sub-neptune planet with 45% habitability (partially habitable) in the JRPG2 universe.
At 45% habitability the environment is demanding but navigable with the right equipment and preparation.
First documented by NASA Exoplanet Archive, this world has since drawn further expeditions from across the JRPG2 explorer community.
Sub-neptune World: K2-18b
K2-18b is a sub-neptune world — a planet whose surface and atmospheric conditions are shaped by its classification within the Beck Protocol dimensional framework. Every aspect of its terrain, resource pool, and creature ecology reflects the defining characteristics of its type.
In JRPG2, sub-neptune worlds occupy a distinct niche in the planet catalogue. Their combination of environmental conditions and dimensional properties gives K2-18b a gameplay profile unlike standard terrestrial or gas-giant destinations, attracting explorers with specialised equipment and specific research objectives.
The Beck Protocol tracks K2-18b as an active world with a measurable dimensional signature. Players engaging with its consciousness-mediated mechanics will find that the planet type directly shapes which operations are available, how much dimensional energy can be drawn, and what kinds of reality manipulation are possible here.
