The Previous Civilization (ca. 13,000 BCE)

Long ago in Terra's history, around 13,000 BCE, there existed a previous civilization that mastered hyper-advanced technologies such as planetary construction and hyperspace travel.

• Creation of DWDB-221E
• The AMa Project
• The original Firstborn project
• "The First Catastrophe": The previous civilization was wiped out of existence due to the "threat" from above.
  • Formation of the "Starpod": The Starpod, or commonly known as the "fake sky," is the borderline that demacrated the previous and modern civilizations as the former is described to be an era when the stars were still observable.

Before Common Era (BCE)

Many of these events happen following the collapse of the previous civilization and the rebirth of a new one. They are said to be happened "thousand years ago"; thus, they will be presumed to have occurred before the Common Era.

• Foundation of Sargon: The Aslanian Conquest that unified the tribes of southwestern Terra would lay the roots to the foundation of Sargon, the first nation with an established sovereignty.
• Foundation of Yan: The first True Lung, "Yan", would unify the peoples of the west under a single banner, giving birth to an empire named after him. However, he would die prematurely just when his country started to prosper.

  • The Great Hunt: The great war waged by a True Lung (Emperor) who subjugated the Yan "deities"/Feranmuts in order to force them to serve the dynasty. Despite countless sacrifices, the war was nevertheless a success through the aid of numerous mortal heroes and a haughty, traitorous Feranmut named Sui. The result was the full subjugation of the deities, the execution/expulsion of stubborn ones, and the fragmentation of Sui into twelve siblings under the Emperor's order. However, it also laid the future threat of Sui's revival.
• Foundation of Kjerag: Kjeragandr, the national goddess of Kjerag, led her people to settle in the mountains, a safe haven from the devastating Catastrophes of Terra, thus leading to the foundation of this small yet peaceful theocracy.
• Foundation of Victoria and Tara: The Draco tribes of the valley fought each other, yearning for a power similar to that of the Sargonian Padishahs. As a result, the kingdom of Victoria was formed, some from the Gaeil clan, led by a certain Draco, seeing the bloodshed caused by the fight for the throne within their clan, fled from Victoria and founded Tara southward.
• Foundation of Laterano: The Sankta race, under the guidance of their first Saints, united together in order to resist the Sarkaz's harassment. The nation's foundation was marked by the building of the Tower of Revelation, a belfry that would never ring for the next few generations.
• Foundation of Leithanien: Leithanien was formed as a confederation of ten tribes bound under the Güldenesgesatz.
• Legend of the She-Wolf: The foundation of Siracusa's mafia tradition by the Six Families of the She-Wolf as well as the establishment of the city of Sette Colli.
• Birth of the Hippogryphic Empire: After escaping from the Sarkaz/Teekaz' threat, the Hippogryph Liberi would settle in the northern mountain ranges, eventually naming the land safter them and build a prosperous, but short-lived empire. They would subjugate the Ancient Races under racist and unequal policies, as they were seen as "inferior". This segregation would also affect the Ursus race.
