Illuminous simply knew nothing of the world of Equestria. His world consisted of just his father and his sister, with no magic and living an isolated life in quiet remote woods. One day, a mysterious entity kidnaps his sister and his father is slain, ruthfully stripping him of the life he had ever known as he sets out to rescue his sister. With an unknown and dangerous power coursing through him, he must face the threat of controlling this new power to be able to save his sister and protect everyone he cares for, or succumbing to it, in turn, destroying everything himself. With new found friends, he embarks in a journey of a lifetime.
