We are the Neo-Demon race
The City of the Sun was a ghost town for the next few months after Zatiel established the rule that no one above Rank 4 could get anywhere near it.
Nevertheless, the business continued as usual. People could still come to the Daybreak Magic Tower, buy goods and sell raw materials. Shipments full of runes, magic weapons and armors, pills, and other resources left the City of the Sun daily.
All those tasks were managed by the Elder Brain and an army of puppets that followed Dante's every command. He even had to create new factories to keep up with the demand for goods.
After Zatiel revealed to the world that he was once an entity above the Prima Universe's laws, orders for his products started coming from every great organization in the Magi World.
The Daybreak Clan's goods were top quality and affordable, but the real reason why they bought them was to form a connection.
