"If my love cannot overpower your duty, nor your duty my love - In the name of love, my name is Aliyah Destiny Demonica!" And she jumped.

Aliyah, the only human to travel the Otherland, the Lightness, the Darkness, the Nothingness, and the Forbidden. The Bylaws forbade any human that found their way there from ever returning, but since childhood, she's been able to resist their restraints and roam freely. Hunted in Otherworld. Hunted in Otherland. No memories of her travels, but something kept her going back.
