Hidden inside the sinners’ pit of the antique library are cursed tomes, heretical books, treatises on witchcraft and black magic, and precious volumes of Kabbalah, all of them written in strange and lost languages. Each book has been placed precisely in the pit, positioned according to exacting rituals; their function to prevent chaos from emerging from the pit. The Keeper is entrusted to stop the souls of the damned from escaping - something they attempt continuously - by touring the labyrinth and keeping the power contained in the books strong enough to seal the abyss. Only the Keeper knows the rituals and the exact position of every volume as he’s the sole person with access to the Sator secrets.
