Midgard

This overview of Midgard will primarily use a Human Era calendar. Year 1 HE (Human Era) marks the first year of the Human Era, and any years after count forwards from there. Year 1 BHE (Before Human Era) marks the final year of the Oceanic Era, and any years after count backwards from there.

Human Era (1 HE-Present)
The Human Era is marked by the presence of Homo sapiens.

Dominion Period (1-1,500 HE)
The Dominion Period is the portion of the Human Era in between the colonisation of Midgard by the Dominion of Man and the Fall. During this period, Midgard was terraformed by the Dominion of Man to be hospitable to life from Earth. Though the oxygenation of the atmosphere had already taken place, and carbon-based life already existed, no layer of ozone was present yet; life on Midgard was limited solely to the planet's oceans. As a result of the rather quick and minimal terraforming efforts by the Dominion of Man, Midgard was split between predominantly Earth-imported life above the oceans and predominantly native life below the oceans. There are some overlaps, but those are relatively rare.

The Fall was the sudden collapse of the Dominion of Man. The grandiose civilisation that they had built collapsed into ruin, its survivors reverting to hunter-gatherer lifestyles for millennia until the advent of agriculture once again. Very few relics from the Dominion of Man remain.

Asgardian Age (15,799 HE-Present)
Upon the landing of the Colony of Salkuviet in Europe, social dymanics began to shift greatly.
