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.爱欧尼亚群岛有一个古老的组织。秩序，混乱，光明，黑暗.所有都必须完美平衡。这个组织被称为"均衡"，他们雇用了暗影忍者三人众来维护平衡之道。凯南,慎，阿卡莉均衡三人众。"狂暴之心跃动不已，失败之人永不忘记" 。
"The Heart of the Tempest beats eternal... and those beaten remember eternally."
While we've all seen what Shen can do out there on the battlefield, it bears mentioning that Ninjas come in all shapes and sizes. Allow me to introduce you all to Kennen, the Heart of the Tempest. Unlike Shen, Kennen originally hails from Bandle City, home of the yordles, and this fleet-footed, pint-sized ninja terror is every bit as lethal as his compatriot. Let it never be said that the Kinkou Order is closed minded with regard to their choice of students!
But what’s the flip side to having two equally lethal ninja champions? Well, it's a well known fact that ninjas work alone! That's right, ninjas have a tendency to step on each other's toes, yordle or otherwise. So while you might be tempted to deploy as many flippin' ninjas as you can get your hands on, use caution!
