Before Erdia, there was Terra.
  Before the fracture, the world sang.
  The Cataclysm of the Old World is a chronicle of a civilisation that did not fall in a single night, but slowly forgot how to listen.
  Set down by Tivovick the Wise, last witness of the Twilight Vault in its unbroken splendour, this manuscript traces Terra’s long descent from an age of perfect harmonic balance into centuries of ideological drift, cosmic intrusion, and quiet betrayal. Though many would later walk the Vault’s shattered halls, only Tivovick recorded it when its stones still answered, its muralglyphs still breathed, and the world’s great instrument remained in tune.
  In an era when cities were aligned to the leylines and knowledge flowed without rivalry, a single act of overreach tore a wound in the firmament—and something vast looked back. What followed was not immediate ruin, but patience: alien pressures sealed rather than understood, progress valued above balance, and foreign doctrines woven gently into the world’s institutions.
  As Mangalan influence reshaped thought and governance, Terra’s harmony slipped. Leylines trembled. Councils fractured. Sanctions hardened into schism. When the final ritual meant to heal the world instead shattered it, war followed across millennia—storms without pattern, creatures born of misalignment, and cultures driven to migration or extinction.
  This is not a tale of heroes and villains, but of consequence—of how harmony erodes when vigilance fades, and how even the brightest world can dim through a thousand small turnings.
  The Cataclysm of the Old World stands as Erdia’s oldest warning, preserved in stone and memory:
  that balance is not inherited,
  that progress without listening is peril,
  and that worlds do not fall— they are slowly retuned into silence.
