Welcome to Tales of Berseria. You may have heard of this world as Tales of Zestiria as well, but this takes place 1000 years before that. The Advent has caused all of Humanity to be able to see Malakhim and Daemons, and has led to the establishment of the Abby. The Advent happened because the one who would later be known as Shepard Artorius sacrifices his step brother to awaken the Empyrean Innominat. He then created the Abby and, due to the power put out by Innominat, created many new Exorcists. By this point. They have basically taken control of the known world, and have eliminated most rebellions to their rule. Also, the world is getting colder for some reason.
