Who we are and who we need to be to survive are two very different things.

— Wendy to Astoria

Professor Gwendoline Astraea Mortan (born Gwendoline Bradley) (b. 3 October), more commonly known as Wendy, is a half-blood witch of the Potter and Mortan families, the only daughter of Isaac Bradley and Astoria Malfoy-Potter. Her parents divorced almost immediately after her birth, and her mother remarried Corvus Mortan, with whom she had Wendy's younger half-brother Linus.

Upon attending Hogwarts School of Witchcraft and Wizardry, Wendy was Sorted into Ravenclaw House for her love of knowledge and strong academic mind, despite also being a close contender for the house of Slytherin.

Life after Hogwarts

"Sirius, you know how it feels to be without magic. At first, the freedom's strange, exhilarating, and then, one day you wake up with that pit in your stomach: that dull, aching feeling of missing the only people that know you. We've been with magic since the very beginning. Separating feels like torture."
—Wendy on her brief yet strenuous estrangement from magic

Later life

"Over the years, I've taught many a student. Each one just as unruly, disrespectful, volatile, and highly unpredictable as the last. I am really quite fond of them."
—Wendy revealing her secret fondness for her pupils

Following the incident with Linus, Wendy came to sever ties and distance herself from most of her immediate family, instead choosing to dedicate herself entirely to a life of work and magic at Hogwarts. In time, she would ascend to the position of Head of the Transfiguration Department, as well as Head of Ravenclaw House, the house in which she used to reside whilst studying at Hogwarts. Professor Sentiatla would also trust her enough to allow her to become Deputy Headmistress of the school and fill in for her on the occasions of her absence. Wendy would also occasionally serve in the role of recruiting students for Hogwarts — for instance, her coming to visit the very confused Hilliard family and having to explain the existence of magic and the true talents of their son.

As a professor, Wendy was a strict disciplinarian, maintaining control of her students with a stern hand that made her someone not to be crossed. She would not tolerate any misbehaviours in her class, and consistently maintained the importance and power of her subject to her students. When it came to grades, she would not teach anyone at N.E.W.T-level unless they had achieved an 'Exceeds Expectations' or higher in their O.W.L results.

Linus Mortan

"You think I don't care? My brother is dead! Dead forever. I thought there was nothing I could do to save him, but now I see that's no longer true. And now, it feels like I'll be trying to make that up for the rest of my life."
—Wendy to Aries after casting her new adder Patronus

Gwendoline is a feminine given name, a variant of Gwendolen. The name is of Welsh origin, meaning "white, fair, blessed, and holy", while the spelling Gwendolen indicates a ring or bow.

Astraea is the Latinized form of the Greek Αστραια (Astraia), derived from Greek aster meaning "star". Astraea was the daughter of Astraeus, the god of the dusk, and Eos, the goddess of the dawn. She was a Greek goddess of justice and innocence. After wickedness took root in the world she left the earth and became the constellation Virgo.

The surname Mortan may have several meanings. It could be seen as a variant of the Scottish habitational name Morton, meaning from the farm near the moor. However, it is believed to be a surname of French origin, taken from the old French word morte meaning "death" or "to die".


Wendy: Beauty may be dangerous, but intelligence is lethal.

Wendy: I'm not here to make friends. I'm here to learn.

Wendy: I'll clap when I'm impressed.

Wendy: If you can quote the rules, then you can obey them.

Wendy: There are things within all of us that could cause devastation once unleashed.

Wendy: Any more misbehaviours and you'll be out of Hogwarts quicker than you can say Kwikspell.
