Timeline

Primal Epoch (8 BYA)
Little is known about this era as it predates recorded time. Within it, the four primal gods Terovar, Shar'Negrath, Verita, and Metsu existed in equilibrium. For this reason, some scholars hold that the Primal Epoch was actually the existence of a single entity that was eventually fractured by an unknown calamity. The theorized creature that existed as a singular entity is known as the "Primal Being." From this calamitous fracture came the subsequent eras, the semi-sapient primal gods, and the eternal chaos that was born from the rise of the individual.

Celestial Epoch (4 BYA)
A uniquely informative era, the Celestial Epoch denotes the emergence of the Divine Gods. Although it is not entirely certain as to how they came into being, it is believed that the cataclysm that shattered the Primal Being created the gods that would come to rule over Terovin.

Primordial Epoch (3.5 BYA)
Much like the Primal Epoch, this is an era that mostly predates recorded time; however, as the Djinn have an elemental connections to the planes which emerged herein, it is possible to determine varying sequences of events. Most importantly, it can be determined that four elemental gods emerged at this time: Atesh, Ajani, Agora, and Azil.

Draconian Epoch (600 MYA)
A theorized era, this is believed to be the time in which dragons ruled Terovin. These immense beasts, now more fable than fact, were created by the elemental gods and waged war across Terovin. It is certain that dragons existed, as the Epoch of Empires began in response to their presence above land, but their supposed purpose can be considered the reproduction of fears held by those that fled from them. The Djinn deny this era occurred vehemently, though some believe this is because the dragons greatly overwhelmed them.

In this era, the hypothetical Yon'il existed.

Fossorial Epoch (1 MYA)
The first era of specifically recorded history, the Fossorial Epoch saw the rise of the Seti, Drow, Dylosians, Vormites and Sheksa. Dwarves and Goblins are believed to have first appeared around this time, though they are not heavily recorded other than in dismissive terms by the Dylosians.

Terrestrial Epoch (400,000 YA)
This era was not one of great recorded history, as many of the primitive and wild races that emerged during it were seen as barbarous by the extant civilizations. Nevertheless, the Borsuq, Onrii, Mynos, and other large-bodied humanoids did greatly upset continental powers. More importantly, the need to either subjugate or defeat these cultures led to fractures within the sprawling empires which had come to a state of near arrested development. Culminating in the castrophe that the Dylosians unleashed, this era was ultimately the shifting of land back to surface. The separation between Blyd and humanity is believed to have occurred at some point during this era, as well.

Epoch of Man (10,000 YA)
If taken objectively, the modern era is contained within this epoch. From the emergence of human groups such as the Auguri to the ultimate creation of the Imperium and its collapse after the Dread Tumult, this records the time of warring empires as well as Pax Novana.
