   Summary

   Long before kingdoms and thrones, the world was a land of endless war, ruled by clans and bloodshed.
   Then came the First King, whose unprecedented power brought peace and established the Breathing's unique abilities that shaped society. From his reign rose the Rings: the Inner Ring of nobility, the Merchant Ring of wealth, and the Outer Ring of the abandoned and poor.
   Over generations, the harmony of the First King faded into hierarchy and division, leaving the Rings’ edges to survive on instinct, hunger, and willpower.
   Yet whispers persist that the First King’s fire still lingers, waiting for someone to awaken it and reshape the world.
