250 years after the announcement, the first of the golden generation reached the Fifth Realm, and that was when things changed for the Archmages and Ancestral Mages.
By now, High Mages and weaker felt their world calm down as all these geniuses had all either already claimed their lands or left them behind.
For them, the most chaotic time had passed, and everything returned to normal.
310 years after the announcement, a terrifying wave of power washed over the world, and all the geniuses noticed.
The Mana of the world had been displaced just now, and the composition of Mana had changed drastically.
The majority of Mana had been replaced with Elemental Mana for several minutes before the Elemental Mana converted back into Neutral Mana.
Many mortals died.
The weaker people had no idea what had just happened.
