Words do not describe Akeru.
Akeru was first shown the plan of the World, then made it. From Akeru came the Five Elements. The Five Elements began their mechanical dance, and thus formed the World. With that task done, Akeru slept. It was not until the first life that Kokoro woke Akeru in quest of answers. Akeru looked upon the world with new eyes. Life was not part of the plan. Uchu was never supposed to be. And yet, Akeru's fascination was overwhelming. And so Akeru blessed life and the first Chosen.
Akeru's Hidden form is the true nothingness, the incomprehensible lack of anything.
