"They came from the southern island, that from none come back. Some told the tale of uncivilised savages bearing iron shields and axes. But the legend also says they could lift two men with a single arm and fight monsters barehanded. On the year 912 of our Holy Calendar they sailed on crude boats to our lands. Thousands of little boats. They sacked and sieged, raped and defamed everything they could find. My kingdom has been burned to the soil it came from, my family only saved by my cousin the Emperor. All men south of Sorgin are said to be dead or enslaved. The Capital will be attacked in three moons' time and will surely fall. The priests say the Gods favour us but I am not sure. I saw them. My greatest soldiers were charged down by their gigantic figures. They had no fear in their eyes. My concubines, wives, courtiers and children were eaten or violated upon my very eyes. The palace in which I was born and groomed was razed. Only mounted soldiers can counter their advance, reaping them like millet in a field. The Emperor is stubborn, but we must evacuate to the west where the Sea Kingdoms lie, across the Great Desert. We must run, or we will perish."
The Ferozen Invasion was an event that happened around the year 33 CE according to most accounts and studies. Archaeologists believe the invasion occurred due to an extreme overpopulation of Tasmania, native land of the Ferozen. It appears they had little to no seafaring technology and leaving the island was almost impossible. Multiple Aboriginal canoes were found along the supposed landing ships, suggesting a massive reverse-engineering of Aboriginal ships. Ferozen warbands almost completely decimated the Aboriginal population in eastern Australia. They also brought ironworking to mainland Australia, making tools and weapons much cheaper and sturdier. The initial technological and physical advantage the Ferozen possessed doomed Aboriginal military forces almost immediately. Though the colonisation of mainland Australia went on for hundreds of years, the invasion proper ended with the Fall of Mir, the Imperial Capital in 35 CE, and the subsequent collapse of the Second Empire.
Such widespread destruction, both physical and immaterial, brought forward the Oceanykan Dark Ages.
