Timeline

Earliest organized civilization on Titānia emerges around the Akkadian Sea. Sumerians develop complex language and writing systems; their neurological evolution leads to awareness of Sati. They invent tattoos to combine writing/Sati with the body directly (the Genesis). Pacifist, philosophical, predominantly female (~65%).

After centuries of inter-clan infighting, the proto-Sūrian clans are unified under Jap̄eth, who vows to reign for a century.

Seeing the potential of his people (~70% of the known world's population), Jap̄eth seeks to conquer the continent.

The Sumerians are driven toward the East coast and eventually flee to the islands later known as the Cursed Isles (the Sumer Islands / The New World).

A gigantism mutation surviving natural selection produces the first Prithvi — "the Vast Ones." Highly competitive (twins almost always absorbed in-utero); longer gestation; high infant mortality. Only Prithvi females can birth Prithvi.

Sūrians in major cities coexist and reproduce with Sumerians who remained (or were forcibly held) after Jap̄eth's conquest, producing a slowly growing group known as Mārtya.

Mārtya (and to a lesser extent Prithvi) populations are acknowledged — small but growing, including a branch of the royal family — eventually resulting in villages and towns scattered along the North Western coast.

Zāhria Léopatra is born in September on the Sumer Islands — destined for the Oracle prophecy. Will later flee her fate, marry the prince of a traveling Mārtya royal family, and usurp the throne to become the Arcadian queen.

Mārtya, having access to Sati and therefore higher longevity, have spread further, coexisting with Sūrians in the majority of the Eastern and Central sections of the continent.
