God
Most people began to vegetate, their lives devoid of any meaning merely. Kayden observed in a unique way how souls started to close off and slowly die while their bodies remained alive. In some areas, dozens of undead began appearing without any explanation. Their souls still existed but were broken and strange in form.
The population gradually dwindled without any significant events. Within just a few millennia, most living beings in this world were eradicated. Only those in the highest realms managed to survive, though they suffered the most, as they had no purpose left in their lives.
During this period, Kayden's strength continued to grow. He took the opportunity to study souls more deeply, uncovering several new nuances, especially when observing the undead with souls. It was strange, but it opened up a new world of opportunities for him.
