Byran

The planet Byran is a metal-rich world with a nitrogen-oxygen atmosphere, located in the Galactic Concordat. It is the second world from its host star of the same name. Unlike most worlds for its type, gigantic, subterranean lifeforms known as "Byran Moles" live. Byran Moles are approximately hundreds of kilometers in size and their bodies make up about 45% of the planet's crust. They feed off microorganisms, bacteria and insects from the atmosphere thanks to surface orifices.

Because of the Byran Mole's unique physiology and rareness, the planet Byran is now a major research site, and tourist attraction. Byran Moles are so large that a human-sized being can travel inside and navigate the interior without causing much harm to the organism itself.
