Diana Bishop was born to Rebecca Bishop and Stephen Proctor, both extremely powerful witches, Rebecca having mastered the higher magics and Stephen being a weaver. From a very early age, she displayed signs of extraordinary power and ability, notably time-walking at the age of three. At the young age of seven, both of her parents were killed while in Africa. Subsequently, she was raised by her aunt Sarah Bishop and Emily Mather, Sarah's partner. This terrible loss caused Diana to reject her magic altogether. Diana went on to obtain a bachelor's degree from a college in Maine and a graduate degree from Oxford. Once she obtained her PhD, she became a professor of history at Yale.
Powers and Abilities Edit
At first, Diana refused to use her powers because it reminded her of the deaths of her parents. However, she wasn't above using her gifts for small tasks, like retrieving a book in the Bodleian archives and dealing with minor troubles in housework.
As the events in the first book progressed, Diana's powers grew at a geometric rate and Miriam and Marcus discovered that Diana's potential is practically limitless, as she possesses genetic markers for numerous witch powers. As time went on, it has been discovered that Diana is not simply a witch, but a weaver, meaning that she is capable of making new spells and that the powers she has exhibited were simply instances of her borrowing them when the need arose.
After embracing her heritage and training with Goody Alsop's coven in the past, Diana's power grew immensely. She gained access to a familiar, a firedrake named Corra, and even after she left her master, the power her familiar had never left her. She mastered the art of weaving spells to the point where the cords themselves emerged on her hands, allowing her easy access to her powers. Her strength reached a new high when the information in the Book of Life was absorbed into her, granting her the power to kill Peter Knox, a man who killed her parents, both of which were powerful witches themselves. Diana is born to a weaver for a father and a witch who mastered the higher magics for a mother. This gave her the distinction of being able to access the power of the 10th knot, the knot of creation and destruction. Her pact with the goddess in exchange for saving Matthew's life gave her access to the goddess's arrow. This arrow does not miss its target and, when used in conjunction with the tenth knot, killed Benjamin Fuchs, ripping him open in an explosion of power.
A Discovery of WitchesEdit
While Diana Bishop is doing research in the Bodleian Library at the University of Oxford, her life is changed by a single manuscript, Ashmole 782 . Almost immediately, Diana sees that Ashmole 782 is a palimpsest, a manuscript within a manuscript, and not only that, the writing underneath has been hidden with a spell. After making some notes regarding the text, Diana decides to send the enchanted document back into the stacks of the library.
In the climax of this book, Juliette Durand, a vampire from Matthew's past, arrived near Sarah's home to assassinate Matthew on orders from Gerbert, her maker. She managed to bring Matthew to the brink of death but Diana called upon witchfire to destroy Juliette once and for all. In an attempt to save Matthew's life, she made a bargain with the goddess, putting anything on the line to save her beloved. Diana managed to save Matthew, but he almost drained her of her blood. Luckily, she was saved with the quick intervention of their friends who stayed with them in Sarah and Em's home.
Shadow of NightEdit
Diana Bishop and Matthew Clairmont have just timewalked to Elizabethan London and the Old Lodge. Their first encounter is with Christopher Marlowe, an old friend of Matthew's. Diana is thrilled to meet the famous member of the School of Night but can see that Kit is in love with Matthew. Kit is ecstatic to see his friend and is cruel and dismissive to Diana, thinking she is a prostitute. When Matthew introduces Diana as his wife, Marlowe is confused and extremely jealous. Diana encounters the entire School of Night, and others, such as Gallowglass, Hancock, Jack Blackfriars, Annie Undercroft, and Goody Alsop. Diana learns that she is a weaver, and learns about her growing powers. She becomes pregnant but miscarries. Mathew's subsequent withdrawal makes Diana feel alone. They travel to Prague in search of Ashmole 782, more commonly known as The Book of Life. The Holy Roman Emperor hits on her, and lets her see the Book of life, but they don't have enough time to study it before Edward Kelley, a daemon, tears out the 3 pages that were missing in the present. Matthew and Diana make up, and their relationship is stronger than ever. Diana becomes pregnant again, and they travel back to their present.
The Book of LifeEdit
Diana and Matthew arrive at Sept-Tours from having timewalked in the past. Diana is pregnant by Matthew with twins. Diana finds out that her Aunt Emily has died and grieves for her profusely. Thinking of how Emily died while Diana was away, Diana asks Matthew to never leave her without saying good-bye. He promises to never leave her.
Philippe's former squire, vampire Alain Le Merle, brings Diana her possessions kept safe since the 1590s: her spell box, other special valuables, and a golden arrowhead on a long chain. He also gives her Philippe's letter that contains evidence that Philippe freely chose to make Diana his adopted daughter. The letter contains a coin, to be returned by Diana in person to the ferryman of the dead in the afterlife, and says to tell Matthew that Philippe would see Diana safe on the other side. The letter also reveals that somehow, Diana was able to keep Philippe company and be of comfort to him after Philippe was rescued from Nazi torture that severely injured him.
Diana remembers that Philippe had told her to "think and stay alive," which the author has said also means that when people think instead of acting violently, they increase the chances of people staying alive.
Diana announces that she is going to the Bishop house in Madison, New York, to try to find information Emily or Diana's mother may have earlier discovered, possibly about The Book of Life. Diana starts using her magical weaver skills to create new spells while at the Bishop house. She enjoys a feeling of belonging to the witch community for the first time.
Diana and Matthew go to Chris Roberts' Yale lab. Lucy Merriweather at the Beinecke Library helps Diana research the location of the missing pages from Ashmole 782, The Book of Life. Diana realizes her purpose as a historian is to rediscover forgotten truths. Diana urges Matthew to form a scion, a separate branch of the de Clermont family to protect Jack, and their other close relatives from other vampires and the Congregation.
While Matthew is in New Orleans working on forming the scion, Diana, Sarah and Diana's close friends and family members go to stay at the London house that Matthew gave Diana. Ysabeau starts to teach Diana how to help lead a scion. Diana also works on discovering the pages missing from Ashmole 782, finding the book, and putting it back together. The information in Ashmole 782, also known as The Book of Life, transfers out of the book and into Diana, and she becomes a walking palimpsest. Matthew returns to her side when he hears that there may be complications with the pregnancy. It turns out everything is OK, and they revel in the wonder of their children.
Matthew goes to Poland seeking Benjamin and is captured. Diana goes to Venice to persuade the Congregation to help the de Clermonts and their allies rescue Matthew. Along the way, she once again encountered Satu, Domenico, and Gerbert while gaining a reliable ally in Janet Gowdie. Diana even resorted to binding Satu's powers to get her former captor to comply with her demands.
After Diana's vampire kin eliminated Benjamin's children, she faced Peter Knox, the man who killed her parents. She used a considerable amount of her own power and that of the Book of Life to drain Peter's life force, killing him and avenging her parents (even her father's spirit visited her for a brief moment). Despite the strain, she also used the goddess's arrow to destroy Benjamin once and for all, this time with no hesitation.
Diana helps rescue Matthew and takes care of him as he recovers. She leads a Congregation meeting in which she is able to obtain revocation of the covenant that outlawed mixing between vampires, witches, daemons and humans.
Philippe appears to Diana as a ghost, telling her that the goddess wants Diana to continue her work seeing that justice is done, taking over the task that had been Philippe's while he lived. Diana and Matthew discuss the birthday party coming up to celebrate the date of Matthew's rebirth as a vampire. Diana realizes that a willingness to change is the secret of survival, and that the combination of their opposite characteristics makes them both stronger. Diana and Matthew were the tenth knot, unbreakable, without beginning or end.
