It is the year 526 of the Liturgical calendar. I, a half-man, half-beast mercenary, was running away from a witch. Now why was the witch even after me, you ask? Well apparently Beastfallen heads are extremely valuable for performing Sorcery. As I raced through the woods, I stumbled upon another witch who saved me. She called herself Zero. Zero was searching for a stolen book called the Grimoire of Zero. Written by none other than herself, the book contained knowledge of Magic, a mysterious new art that surpasses Sorcery. If anyone with the aptitude read its contents, they could easily bring about supernatural phenomena. It was a dangerous magical tome that could drive the world to ruin. The witch offered to restore me to my human form. In exchange, I would be her bodyguard, accompanying her on her journey to retrieve the stolen grimoire.
