Time for the Alien Robot Corpse Experiment
Two years after the onset of the Ice Age, the first hundreds of millions of living beings in the Spiritual World had rapidly perished.
Most of the world had prepared for this moment, but not everyone had been as efficient in dealing with the disaster.
The weakest and least prepared, whether in terms of strength or even alliances and food reserves, perished in the first few months of this new era.
However, most of the beings in the Spiritual World survived the onset of the Ice Age relatively well, with states such as the Black Plain Empire coping well with this initial moment of calamity.
Powerful tribes also survived the beginning of the calamity well, but everyone in the world was already suffering from the initial effects of climate change.
