Season Finale. The third season of the show is based on the final book of the trilogy, ‘The Book of Life.’ In season 3, Diana and Matthew will come back to the present day with rage in their hearts. Knox may face repercussions for killing Emily. Since Diana has completed her training, we can expect her to tap into her potential as she will face threats from Knox and the others. The Congregation, which includes both vampires and witches, will threaten Diana and Matthew’s inter-species relationship, especially in the wake of Diana’s pregnancy.
Matthew and Diana travel back to Elizabethan London, where they are hiding in time from the Congregation. Here, they must find a powerful witch teacher to help Diana control her magic and search for the elusive Book of Life. Back in the present day, Diana’s beloved aunts must take shelter with notorious witch hunter Ysabeau De Clermont at her ancestral home.
