Aln

Aln is the name of the star and the solar system that Arthos is a part of, and contains 6 planets known to Arthonean astronomers.

Gian

A partial anagram Geiana, the Parathist goddess of decay and restoration. The closest planet known to the sun Aln, and observed as a rock planet with a boiling surface of lava and magma. Some believe this is where the demons ethereal beings rest before coming to Arthos to cause chaos and committ evil deeds.

Arthos

The planet itself that you know and reside on. It has an estimated circumference of 15,000km which is 10,000km less than earth. Arthos also has a small ring of asteroids cuased from the Arthonean Cleansing, to date is the biggest natural disaster to ever hit Arthos. The planet experiences meteor showers constantly but since the the Source landed on Arthos, the meteors rarely get through the atmosphere, and those that do usually are composed of rare metal or crystal.

Ronus

A partial anagram for Chryonus the Parathist god of wealth and poverty. The planet is predicted to be the closest celestial body to Arthos that is not Lusin and Livone. When the Arthos passes Ronus due to it's faster orbit around Aln, astronomers hastily gather as much data as they can before one of the moons obscures the view of the planet, or it starts to exit visible range. Some philosophers suggest that Ronus could potentially have life on it like Arthos, but many find that to be a pointless and fantastical prediction.
