Morgana kept answering the Freebird party's questions and explaining the cycle of chaos in a way that they could comprehend.
The reality was that this cycle was something that the developers of Aegis had coded into the world before it had become real.
When Aegis was just a game, having a cycle of chaos in cities made sense since it meant that even if players went into a town and saved everyone, it would slowly revert to its previous chaotic state so that other players could experience it, too.
Without the cycle of chaos being hard coded into Aegis, players would have ended up with no activities to do in the game, as everything would have been peaceful.
After the Red Calamity that turned Aegis a reality to its players happened, plenty of the game systems worked differently, making Morgana believe that the cycle of chaos was on that list.
