Long ago lived a young girl, a sick girl who stood tall despite her condition... or her state in the middle of the archon war. Strongly she lived long enough to see the power of the archons at first hand, but when her condition worsened it all went downhill. But freedom, contracts, eternity, wisdom, justice, war, unknown. The seven archons thought of who would tell their tale once they have fallen, so after discovering the sick girl they combined one ounce of power each.

Justice, to know what right and wrong.
Eternity, to live beyond death.
Contracts, to learn when the job is done.
Unknown, to know mysteries beyond mysteries.
Wisdom, to gather knowledge and hold strong mind.
And freedom, to let the girl the young warrior rise above others and break free from her doubt she holds close to her.
