Third Person Point of View

The Seven Kings, each with an Aura, a Clan, a Sword of Damocles, and a Sacrifice.

Each Auras color depends on which King it is; the Red King's Aura is red, the Blue King blue, and so forth. Each King has a Clan that normally goes through a formality to become a Clansman; the Red King simply makes them shake hands with his flaming hand and the Mark of HOMRA appears on a part of their body and they become a Clansman if they are worthy. The Sword of Damocles represents the King's state, when he begins to lose control over his powers it's the swords job to Discipline the king, it will begin to break and crack the more he loses control and once the orb in the center of the sword light goes out, it falls on the King and kills him, and makes what is known as Kagutsu Crater happen, it will wipe out everything around it at a huge scale.
The Sacrifice's creation is unknown, just that the Dresden Slate made them for one simple reason, to die for their King.
The Slate gives them power close to that of the King, and when the Sword of Damocles falls if they die their power is given to the King and it heals the Sword and the King back to its original state. The King does not know who their Sacrifice will be unless the Sacrifice tells them themselves, the Slate only tells the Sacrifice who his/her King will be and what they are meant to do when the Sword Falls, they have a choice on whether or not to die, or let their King die.
During the Kagutsu Crater incident the Red King Genji Kagutsu prevented his Sacrifice from killing herself by having his Clansmen sedate her during the battle, the Sacrifice for the Blue King was killed along with the Blue King Jin Habari.
Normally the King's keep their Sacrifice's identity hidden from the other King's to insure the enemy King's won't kill them out of spite for that King.

Each Sacrifice has a duty, each Sacrifice must decide to fulfill that duty, or let their King Die, this is a story of both happiness and tragedy.
