100th Millennium Wiki


Nysha is the eighth planet orbiting Aolia, in the Treana Molecular Complex inside the Snow Nebula, in the Florathel Galaxy. It is a frigid titan that harbors exotic life, and was the third planet in the Snow Nebula identified to have life, after Davon and Klast. It is also one of the coldest known planets to harbor life.


Nysha is a typical Titan-like world, with a non-dense slushy mantle and an icy core. Giant oceans of methane and nitrogen cover Nysha's surface as well. Nysha orbits far from its parent star and gets little to no heat. This is obviously typical of planets of its type.


Life on Nysha is mostly single-celled bacteria which thrive in every environment, but have been greatly expanded in size due to the extremely cold temperatures. However, there is a significant shortage of multicellular and complex organisms. Research from the human colony established here also shows significant radioactivity in the rocks present, which suggests a theory:

There was once an intelligent civilization present on Nysha which detonated a massive nuclear bomb in the process of a war, 2.8 billion years ago. That nuclear bomb had a power of 213, 548 megatons of TNT, which wiped out the whole civilization and killed a large part of the animal and plant kingdom at that time. This is not 100% certain, though.

Nysha has a colony established. Initially, it was just a crew of 6 individuals, but more and more came here until today, there are about 1.1 billion individuals, forming a few large cities on the vast majority of islands that dot this planet.


Nysha has 4 moons. The innermost one, Kilae, resembles a super-cold moon (before it was terraformed). The other 3 are asteroids.

Ring system

Nysha has a thin ring system, thought to have been formed after an asteroid moon broke up in its roche limit.
