As a mere student, Niel didn't expect to receive his first Arcanus companion at the age of only sixteen. He definitely didn't expect for it to be the harbourer of a conspiracy stretching older than a thousand years. Alongside the feisty harpy Akira, Niel must work together with his companion Thora in order to uncover clues about the mysterious and unsettling plan lying beneath the innocent guise of Annemos. But theories only stretch so far, and a far more sinister truth is hidden behind doors closed for centuries. This truth could bring about the end of life as they knew it.
