Planet 4546B is a category-3 ocean planet on which the stories of Subnautica and Subnautica: Below Zero take place.

Around 1,000 years ago the Architects set up research outposts on 4546B to study a deadly pathogen named the Kharaa Bacterium. Kharaa is not native to 4546B, being discovered on another, unnamed planet. When Kharaa broke out on 4546B a quarantine was enforced, resulting in the events of Subnautica 1000 years later.
