Previous Lore
There exists an ancient order originating in the Ionian Isles dedicated to the preservation of balance. Order, chaos, light, darkness - all things must exist in perfect harmony for such is the way of the universe. This order is known as the Kinkou and it employs a triumvirate of shadow warriors to uphold its causes in the world. 
Kennen is one of these shadow warriors, entrusted with the sacred duty of Coursing the Sun - tirelessly conveying the justice of the Kinkou.
Kennen was born in Bandle City and it is said that in his first living moments he bolted first from the womb and second from the midwife who delivered him. His parents had thought that he would outgrow his boundless energy, but as he matured, his energy found no limits and was matched only by his unnerving 
speed. Despite his astonishing gifts, he remained unnoticed (or at least uncaught, as he was quite the prankster) until, on a dare, he ran straight up the great outer wall of the Placidium. When word of this feat reached Kinkou ears, Kennen was quickly and quietly brought for an audience. He found that the role of the Heart of the Tempest suited him, frenetically delivering both the word and the punishments of the Kinkou across the realm. He now works with his fellows 
Akali and 
Shen to enforce the balance of Valoran. This hallowed pursuit has unsurprisingly led the triumvirate to the Fields of Justice.
