Disaster / Destruction
On this catastrophic date, a portal to the abyss was opened by a magic practioner. The portal was big enough to let armies of demons come into the material realm. The demons destroyed all of the former continent of Dremaria and made it into a hellish new continent known as Fireskull.
The invasion of demonic armies was stopped by an alliance between all nations. Great sacrifices were made during this war, leading to mistrust between races that would in time escalate into the Magna Bellis.
