Imperium Timeline

This is the Timeline for the Imperium of Valkyria for my World Building project called Aetherial Reign.


Era of Creation

25,000 BCE - 11,000 BCE

This is the Era of Creation. During this the world was formed and designed by the Gods, the races emerged from their creation, and the world really took shape. This is also when the God's Wars happened and the Heavens themselves burned in the fires of war.

Era of Myths and Heroes

11000 BCE - 4,771 BCE

The Era of Myths and Heroes is just that. All the mythical stories of the Gods, the Heroes who were their champions and the continuations of the God's Wars were in this Era. Elves suffered heavily in this era as they battled for survival against the Dark Gods.

Era of Strife

4,771 BCE - 1 AD

The Era of Strife is when the world suffered under the rule of the Dragons, the Dark Gods and all things Evil. The Moon Elves knew the greatest extent of their power in this era, and the world was thrust into darkness as brothers fought and nations burned in the fires of strife and war. Blood ran like rivers and drenched all those in its wake. This Era came to an end with the foundation of the Valkyrian Imperium.

First Era (Era of Expansion)

1 AD - 648 AD

This is the beginning of the Imperial Eras, the Year 1 that the majority of the world uses to divide the time is with the foundation of the Valkyrian Imperium at Year 1. King Alkanius VI of Altera founds the Imperium renaming himself Holy Emperor Alkanius I. His family, House Marrellius will rule for half of the First Era, ending with an assassination of their last ruler.

Second Era (Era of the Golden Age)

648 AD - 1960 AD

This is when the Imperium achieved its greatest extent of power and authority. For the first half of this era there was unprecedented peace and prosperity among all stratas of society and not just at the top. However internal strife, corruption and greed would see the second half of this Era fall into complete ruin and terror as the nobility and nominal lords competed against one another for power and prestige, the Holy Emperor was also sidelined in the latter years of this Era and while he was mostly untouchable by the nobility he was virtually powerless as the nobility fought one another openly. Eventually this infighting grew and the Imperium collapsed giving way to the Third Era.

Third Era (Race Wars)

1960 - 2751

The Third Era follows the collapse of the Imperium into many warring Kingdoms, Republics, Magocracies, Theocracies, and other kinds of various states all fighting one another and no longer paying heed to the Imperial Authority of the now powerless Holy Emperor. While the Imperium contracted back to it's strongholds giving up lands to revolution and rebellions, along with shedding unnecessary lands, the Imperium did survive, even if it was a shadow of its former self. This is also an Era known as the Race Wars, when the Alven Dominions waged countless wars against one another and against the Humans.

Fourth Era (Shadow Years)

2751 - 2941

The Fourth Era, also known colloquially as the Shadow Years, are a very dark time for the world. These years rival those of the Era of Strife for the number of conflicts and deaths that spanned the world. The Solar-Lunar Wars that saw the eradication of one of the Moon Alf races happened in this era, as did the near destruction of countless nations, many indeed did fall in time.

Fifth Era (Imperial Reformation)

2941 - 3148

The Fifth Era, also known as the Imperial Reformation saw a resurgence of power in the Imperium as the Holy Emperor shed the Old Imperial culture and created the New Imperial Culture, along with taking the title Emperor and dropping the word Holy from his title. This and a massive increase in diplomacy rather than fighting, controlling the nobility and addressing the concerns of the lower and middle classes the Imperial Government began to regain its power and authority allowing the Imperium to look into the future with hope to restore its former glory.

This is also the Present Era.
Present Day is 5E 207 (Or 3148 IF)

5E = Fifth Era (Used with New Imperial Calendar and Culture)
IF = Imperial Foundation (Used with Old Imperial Calendar and Culture)

Present Day


This is the Present Day (on the Old Imperial Calendar) whereas it is known as 5E 207 (207th Year of the 5th Era) on the New Imperial Calendar.


Alkanius I

17 BCE - 14 AD

The Rule of Alknanius the First is characterized by the unification of the Kingdoms of Altera, Garium and Calix, then the subsequent reformation of the Triple Kingdoms in the Imperium of Valkyria centered at Altera.

The early years of his rule as King of Altera was rough. He had inherited his father's wars with the Kingdom of Garium and the Kingdom of Calix, which Altera had been fighting for nearly eighty continuous years. Through his determination and martial prowess the Kingdom of Altera was able to deal a final blow to the Twin Kingdoms at the Battle of Agara, where a numerically superior Twin Kingdoms Army was routed by the Alterans who had flanked the larger army successfully and a final charge led by Alkanius himself.

Following the victory at Agara, the Kingdoms of Garium and Calix became subservient to the Kingdom of Altera. It was at this point after nearly two decades of his rule that King Alkanius reformed the Triple Kingdoms into the Imperium of Valkyria, centered at Altera. He assumed this new Imperial Throne as Holy Emperor Alkanius, First of His Name and Patriarch of House Marrellius. He would continue to expand this fledgling Imperium into the surrounding lands annexing several small city states and a couple smaller kingdoms in the process before a plague took his life and that of his son. However his grandson Praxis would succeed him.

Praxis I

14 AD - 33 AD

Praxis the First was the grandson of the Holy Emperor Alkanius the First. His father Nomericus had passed away, as did Alkanius in the Plague of Forente which had killed nearly one in ten in the Imperium.

Following his ascension to the throne at the age of seventeen, and his mother having served as regent for one year, Praxis was ill-prepared to handle the wars his grandfather had started and the internal strife that had developed in wake of the Plague. Strife turned to anger and anger turned to rebellion. It spread like wildfire throughout the Imperium especially in the former Kingdoms of Garium and Calix which had been annexed under Alkanius. Their nominal lords rose up in open rebellion not only against the Imperial Government but also against the Holy Emperor Praxis I. Fortunately for Praxis many of his grandfather's most trusted military commanders were still in control of their Legions and helped to crush the rebellions ushering in stability in the realm.

After ten years of rule, Praxis began to seek diplomacy over war with the Imperium's neighbors hoping some would join willingly rather than always having to be annexed. This seemed to work for some time with the smaller states opting to join the Imperium for protection and prosperity that seemed ensured. Peace seemed to spread and soon the Imperium found itself in a semi-golden age, many scholars now say it was a Silver Age, though Praxis would be assassinated by agents of the Garium Independence League, and his son Decius would ascend at the age of 18, being the second youngest to hold the title of Holy Emperor.

Other Calendar Dates

This is to show important date transitions from other Calendars, like the Ryune and Korrsani Calendars.


1489 BCE

This is the Korrsani date of when their Wandering Years begins. This is prior to the Imperial Eras and happens during the Era of Strife. The Imperium holds little record of this time and even then the record is purely from oral sources.


381 AD

This is the Beginning of the Korrsani Taciri Era. (Slaver Years) this is when the last of the Korrsani Kingdoms fell to the might of the Imperium and their people were used as slaves officially losing their status as Sentient Beings.



This is the date that the Korrsani achieved independence from the last of their oppressors becoming a independent people again and this culminated in the formation of several Korrsani Kingdoms throughout the south.
