100th Millennium Wiki

Aya is a G-type yellow dwarf in the Ejeunor galaxy and is the home system of the Shevins.


The star iholds an average size and takes 28 days to rotate. During ancient times, Shevins worshipped Aya as the god/goddess of creation and thought of it to be at the center of all existence with the other planets being seen as Aya's children.


Aya is orbited by 10 planets, 2 of which, have life. Three sentient species have arisen in this system, being the Shevins of Eydafrei and the Urqels and Qods on Deiona, however only the Shevins are actually capable of space travel as the two other races on Deiona are still fairly primitive despite being classed as sentient.

Past to Present

5.9 billion BCE: Aya is forming, the planet taking shape in the surrounding stellar disc.

4.10 billion BCE: simple life emerges on Deiona.

4.9 billion BCE: Asteroids containing microorganisms bring life to Eydafrei. Evolution soon starts to take place in the primordial seas.

2 billion BCE: Multicellular life begins to flourish on Deiona and Eydafrei.

1.7 billion BCE: Gamouri's moon crosses the Roche limit and is torn apart, forming a large, beautiful ring around it, and leaving the planet without any moons.

4-5 million BCE: Shevins evolve

Distant Future

3.7 billion CE: Aya is expected to expand into a red giant, engulfing Sojos, Balaris and possibly Deiona. Eydafrei will be reduced to a scorched hellscape of lava flows. Tempratures on Gamouri could rise, turning the planet into a hotter desert world. The sheer heat from Aya might melt the surfaces of Quinus and Onar, possibly turning them into humid water worlds. Some of the moons of Inos could become temperate oceanias along with Alvara. Xisym may become a cold water world with small icy continents and drifting glaciers.
