Asrar Averille was once an unremarkable young man, son of the newly-minted noble—Baron Harold Averille. Yet, one fateful day, as he stood beside his family at his unconscious sister's bedside, an incident occurred that unlocked clogged memories from his previous life as a toxicologist.

In a world where the Monastery of Light held sway over all, the organization cast a shadow of domination over the noble houses and held the strings of fate that determined the future of the neighboring kingdoms.

In a world where the piety of bishops and high priests deemed any art of healing, out of their jurisdiction, a blasphemy, and those who dared to ply its trade met a grim fate at the end of a rope or the blazing embrace of a crucifix.

Can Asrar, with the wisdom garnered from his former life, defy the prevailing order and elevate his family to newfound heights, all the while shielding them from unseen harm?
