Kriseroi News:  Neidus's population will soon pass the 1 billion mark.  A colony on Chithess now sends frequent teams to Uzin's frozen global-ocean surface.

Note

Theonax's surface is covered by water and ammonia-hydrate ices, which are constantly repaved by cryo-volcanic processes. The world's size and density suggest the core contains heavier elements and retains much of the heat of the system's formation.

Note

A typical methane-ammonia ice giant, Uzin has 37 moons of various sizes. Chithess, one of the largest, orbits at a retrograde, suggesting it was a planetesimal that was captured by the gas giant gravity well. The planet itself is believed to be an extra-solar capture as well, though millions of years before Chithess came on the scene. Evidence collected by planetary geologists suggest that Chithess was for many centuries a water-world heated by tidal flexing as its orbit circularized by Uzin. The planetary ocean, once hundreds of kilometers deep, must now be frozen solid. Some have recommended drilling test bores to see if life ever developed in Uzin's seas, but the question is considered academic.


Note

Geus is a methane-ammonia gas giant very similar to its near-twin, Uzin. It presents a nearly featureless robin's-egg-blue face to the universe.
Note

Tenoth is little more than a glorified "ice dwarf" that has drifted inwards from Kriseroi's Oort Cloud over the millennia. Its extremely elliptical orbit is ultimately unstable. Computer projections suggest it will impact the atmosphere of Geus in a few billion years.

Note

Neidus lies improbably close to the red dwarf Kriseroi. This allows it to approach habitability though it is quite frigid. It is tidally locked, with a "hot pole" and a "cold pole". Along the terminator, the temperature averages just above freezing. On the lee side the temperatures are well below freezing. Neidus has developed a limited native ecology. Much of it clusters permanently attached around geothermal vents. There are, however, more advanced forms of life. Several arthropodal herbivore species wander back and forth across the terminator because they require nutrients available in both environments for sustenance. More dangerous are the omnivorous predator species that devour the arthropods. Most animal life on Neidus has limited vision but a finely developed thermal sense.
