  • Kreanus is covered in water approximately 100 km deep, half of which is ice and the other half still liquid due to the extreme volcanism and high amount of magnetic movement of the core. Thermal vents dot the remaining ocean floor with a high-temperature fluid/rock interaction forms reduced gases (H2S, H2, and CH4) that dissolve in hydrothermal fluid. Representative redox reactions that produce H2S-rich community of thermophilic and hyperthermophilic communities along with remaining communities of other organisms. Since there is no sun, the primary producer of food chain source is a sulfur reducing bacteria. Thermolysis and radiolysis decomposition of the liquid water are thought to provide the necessary oxygen still remaining in the atmosphere and provide oxygen for the remaining communities of organisms.

  • Kreanus is a rogue planet which means it has no parent star(s). It was most likely ejected from its solar system several billion years ago, and has been floating free within the Paulson Nebula ever since. Because the planet lacks a primary solar radiation source such as a sun to heat its surface, the terrestrial world has frozen over many eons ago. Despite its predicament, however, the planet was once a Class M world and still retains many life-supporting features. Below the plants thick ice surface lies multiple liquid oceans, volcanic activity, and a still-spinning molten core which provides the world with a strong atmosphere. Life cannot sustain itself on Kreanus' surface due to the extreme cold temperatures, but beneath enough layers of ice and rock, there is still a habitable world to be found.
