In a world similar to our own, known by its inhabitants as Uni, Humans still roam as the dominant species. However, for reasons unknown to even them, each one of these Humans is born with an incredible power known as a Gift and a horrendous drawback that they call Burdens. To those on Uni, your Gift and your Burden determines your value. And so, Keyaxel, a boy with a decent Gift but a horrible Burden sets out on a self-assigned quest once he comes of age to prove his value to Uni as a whole.
