In a world controlled by three people; Duchess Emma Derrick, Duke Ezekiel Jordan, and Duke Joseph Lynn. There's been hundreds of years of peace on earth. Part of the reason for this is that the three kingdoms haven't been in touch with each other since their ancestry heirs made the "7 Promises to Humankind."
However, Ezekiel Jordan makes a visit to Emma Derrick's kingdom, because he's running out of supply and he's in need of assistance. Emma refuses to help him, and that causes conflict between the two.
Resources are low for everyone though. The pollution has gotten so bad that it's become irreversible, even after all three kingdoms vowed to get rid of all pollution causing materials. The world may become inhabitable at any second.
