2180 AD, 39th year of Inosanto's era - Mathilda is leading a peaceful life in the small community of Kalia, at the heart of the sacred lands of Africa. As the almighty Inosanto - the founder of the Terra Fecundis Church leading what remain of the world with an iron grip - imposes, Mathilda is following all the religious precepts. She is probably the most diligent and religious person of all the parishioners. She hopes, one day, God will reward her devotion and grant her the sacred gift of carrying a child to perpetuate the future of humankind. Indeed, for several decades, humankind has been suffering from a lack of birth. While she is meeting her mother in the rice fields, she witnesses the death of an old stranger, who isn't part of the community. A drone of the powerful Milicia Christi, the Church's sword hand, slaughters him in front of her mother and her. This unexpected event will change her life forever and shake up her religious beliefs in this world where the inquisition has regained a complete authority.
