Military: War
A ruinous conflict between the two most powerful leaders of the Magocratos, sibling demigods Urza and Zian. The Magocratos is polarized into civil war and the republic undermined by the terrible charisma and momentum of the two. The Elvish Protectorate steps in and is also subsumed by polarization, both militarily and politically. The war, fueled by the full might of centuries of progress, is only ended with the complete annihilation of the siblings during their final battle. The density of different magical fields warped around the two causes the first recorded Destabilization.
