The Citramagæ is Triggered

Disaster / Destruction

Little is known about what caused this event, but what is known is that it forever changed the course of history. At exactly 0 BCM all of the magæ-forged objects and mana reactors that powered the great precursor civilization suddenly tore themselves apart in a simultaneous and violent explosion. This released a deadly mage-smog that slowly intensified and spread, heedless to all attempts made to stop it, making all unprotected parts of the realm uninhabitable by about 4 ACM.

In O ACM all of the magic infused technology that powered the great precursor civilization suddenly tore itself apart in a violent explosion. This released a deadly smog making much of the realm uninhabitable. The smog kills most within a few days due to the magic sickness it causes called 'the smog-sickness.' This magic plague spread over the course of about two years over the realm wreaking unrecoverable havoc.
