Runeterra's greatest weapons master, Jax Jax is the only survivor of the Kohari champions sworn to the defense of Icathia. But when the Void was unleashed against the Shuriman empire's Ascended Host, Icathia was destroyed, leaving Jax without a home or purpose. He gathered the “last light of Icathia”, a symbol of his hope to one day defeat the Void, and now travels the world, searching for warriors strong enough to face the coming darkness by his side.
