Aether is named for the god of the upper air In reference to its dense atmosphere. Aether is the 4th planet from Animus and the only planet in the Animus system home to life. It has the densest atmosphere of all the terrestrial planets in its system and the highest gravity. Aether Possesses two moons, Zephyr and Notus, these moons give stability to Aether's axial tilt as well as apply tidal forces which would eventually give rise to life.

Aether has an axial tilt greater than that of earth meaning seasons will be more extreme; However, the denser atmosphere of Aether will help circulate the air somewhat stabilizing temperatures. Even still seasons will be much harsher on Aether when compared to Earth.

Aether's dense atmosphere allows life to pursue many forms different to those one would be familiar with on earth but because of its higher oxygen content wildfires will be a consent threat to the landscape they'll brighter and hotter for longer devastating anything that it comes into contact with them.

All of this will contribute to every radiation of life that Aether produces each formed by different factors of the environment working together to create a unique organism.
