Era beginning/end
It was a natural progression of what we started in the age prior. Now nation fought nation, hungrily and greedily to find some imaginary artifact of Bjorns'. -Jess Merrock, Historian
In this time the Republic and Imperium were in their infant stages, but both wanted the same thing, the artifact of Bjorn, the Relic of wishes. Neither knew where to find it, so began the Age of Conquest, where the Imperium and the Republic fought visciuosly over land, hoping the Relic laid somewhere within their borders.
