The city had been lively and boisterous as always until, in one of the newer night districts, a casino building burst into black flames. The fire started on the upper floors, giving enough time for the rich patrons and staff to be evacuated.
Luckily.
Luckily, because of what came next.
A destructive explosion of black fire roared through the night. In a single second, the entire building was gone every brick, every stone, every trace obliterated, leaving nothing but a deep crater where it had once stood.
Emergency response units arrived on the double. Knights, healers, local patrol squads… soon the entire area swarmed with experts providing care and amenities to the people.
The fast response was a stark contrast to the slums. Naturally, it was because the people here were richer and thus their lives had more value.
