I'm trying so hard to be good. But all of this was forced upon me. I'm cursed, and I'm angry.

— Atria to Ember

Atria Jacqueline Hilliard (b. 30 January) is a half-blood witch and Banshee half-breed of the Hilliard and Cauldwell families, the illegitimate daughter of Noah and Ember Hilliard (née Cauldwell). She is also the maternal half-sister of Albus and by extension the adoptive sister of Musidora. Being the product of an affair between two people who had been in different relationships at the time of her birth, Atria was passed on to Noah, who raised her alongside his then-wife Mara Rountree. The truth behind her parentage was kept a covert secret from the wider wizarding world, only to be revealed at a later date.

Upon attending Hogwarts School of Witchcraft and Wizardry, Atria was Sorted into Gryffindor House, like her biological mother.

Atria is a celestial female given star name, deriving from the star in the constellation Triangulum Australe. The plural form may also refer to an atrium, a large open space within a building, or the atrium, an anatomical structure through which blood enters the heart.

Jacqueline comes from French, as the feminine form of Jacques (English James). Jacques originated from Jacob which is derived from the Hebrew meaning "may God protect".

Hilliard comes from the Norman names "Hildiarde", and "Hildegard," composed of Germanic elements that mean "strife", "battle", "fortress" and "stronghold". The surname has been in Ireland since the 17th century.


Atria: You know me. I just love to stay busy.

Atria: Why enjoy today when you could be worrying about tomorrow?

Atria: Your hands.
Henry: Uh, they're on your waist.
Atria: Exactly. Do I look like a nun? Put them somewhere more useful.

Atria: Hands off, ghoul!

Albus: So Leo's bisexual now?
Atria: Of course. He turned all the paperwork in last week and his acceptance letter only just came in this morning. It was all very sudden.

Atria: You catatonic, galloping gorgons didn't even vote! Since you're both too dim to exercise your own rights, and you both have the combined vocabulary of a pumpkin pasty, consider this your final debate as a Holy Hedwig. You're out, end of story. Shoo!

Ember: Atria, sweetheart, I feel it's my duty as your professor and your mother to remind you of one thing... try not to embarrass me.
Atria: You should have thought about that before wearing those shoes. Love you.
Ember: Love you too.

Atria: I only drink the blood of my enemies, and the occasional pumpkin juice.

Atria: Just my witches' intuition, but Musidora doesn't seem like the type to try and hurt anyone.
Albus: Your witches' intuition?
Atria: Every witch has one, you know.

Noah: There it is. Like clockwork. Devastation. You're sad a case is over.
Atria: That's ridiculous. I'm happy that everything worked out just fine.
Noah: You're only happy when there's trouble, and that I know that for sure.

Atria: Don't worry, little one. Everyone's scared of something.
Musidora: Even you, Atria?
Atria: No.

Atria: If it's locked, it must be important.

Atria: Oh, this is just my list of inspirational women.
Albus: It's just your name.
Atria: Yes, I am big enough to admit that I am often inspired by myself.

Albus: I wouldn't go back to that person I was before. All I cared about was winning. But life is bigger than that. And now, I would give everything to just be happy.
