Athom System

Information
Before it was known as the Athom System, this part of the void was home to the Solar System, however a fight between Nebula, Umbra and Igny wiped it out.

Igny created the Blue Star, where he, Nebula and Umbra would live, with their descendants they constructed the City of Lights.

However when tensions began to arise again between descendants and due to the different nature of each god, Nebula created three planets, one for each God.

The Blue Star and the City of Lights were left as an arena if the need of a duel ever had to take place.

Every 500 years the Dimming takes place. This phenomenon is an eclipse in which the orbits of Astrae, Kepler, and Somnia coincide, leaving Somnia halfway between these 2 other planets.

Blue Star
The Blue Star is a planet surrounded by a veil of fire in the center of the Athom System, it's where the City of Lights is.

Astrae
Astrae is the first planet orbiting the Blue Star, it's where Arcadia and Dracaia are.

Somnia
Somnia is the second planet orbiting the Blue Star.

Kepler
Kepler is the third planet orbiting the Blue Star.
