The Purge

Religious event

After the birth of the Seven Deadly Sins, the people of Dawn become increasingly suspicious and wary of the Magi dwelling in the kingdom. A crusade led by the Fate called "The Purge" kills and drives away most of the Magi humans in the nation. Many flee south.   The Fate also officially bans all tenth level spells after The Sins used them to attempt to usurp the gods. The rest of the world adopts this ban.
