Solheim

A legendary ancient civilization (also called the first civilization) that predates Lucis and Wyveria by thousands of years.

Known to the public

 * It was an ancient civilization
 * Niflheim used to investigate Solheim
 * There are ruins dispersed around Eos
 * The capital is next to Apocrypha
 * Solheim was destroyed by the Astrals

Known to scholars

 * Lucis also based itself from Solheim's ruins, in fact, Somnus Lucis Caelum, the Founder King, and Ardyn Lucis Caelum used to live in Solheim.
 * Solheim flourished greatly thanks to the Astrals themselves in the first place.
 * Solheim is thought to have betrayed the Astrals due to weapons and automatons possibly designed to commit Astricide (This fact is only known by a few scholars as it could cause a religious division and/or uprising).
 * The plague of the Starscourge could possibly be related to Solheim and it's downfall, but this is just speculation.
 * There are ruins spread all across Eos, though the capital remains impenetrable due to the hostility of the remaining automatons.
