Frodbrokna (concept)
Frodbrokna is the name given to a series of cataclysmic events that transpired on 1.3.1200 after the Aautokratir Aeschraes unleashed Self Replicating Blood Magic onto The Continent. This wreaked wide spread havoc and devastation across Aeras, killing nearly half of the Aversarian population, untold numbers in the wider world, and stripping many survivors of their control over magic. While his target, Axiaothea, was killed in the blast, it is unclear whether that was due to the spell's success, or the mass devastation.
The sheer power and horror brought into being was so great, that reality shattered—cracking Aervalr and bringing forth the Fog.
