Diana, you've always treated me like family and I know things are really confusing right now, but if it turns out that you are my sister, I'd be really happy about that.
— Cassie to Diana Meade [src]

Cassie Blake (born March 28, 1995) is the main female character and protagonist of The Secret Circle. She is the daughter of Amelia Blake and John Blackwell, the best friend and the paternal older half-sister of Diana Meade, and the paternal older half-sister of Four unknown half-siblings, the ex-girlfriend and best friend of Adam Conant, and also a member and the leader of the Chance Harbor Circle.

Cassie was a happy, normal teenage girl until her mother Amelia died in what appeared to be a tragic accidental fire but not such as an accident. Orphaned and deeply saddened, Cassie moved in with her warm and loving grandmother Jane in the beautiful small town of Chance Harbor, Washington - the town her mother left so many years before - where the residents seems to know more about Cassie than she does about herself. As Cassie gets to know her high school classmates, including sweet-natured Diana, her handsome boyfriend Adam, brooding loner Nick, mean-girl Faye and her sidekick Melissa, strange and frightening things begin to happen. When her new friends explain that they are all descended from powerful witches, and they've been waiting for Cassie to join them and complete a new generation of the Secret Circle, Cassie refuses to believe them - until Adam shows her how to unlock her incredible magical powers. But it's not until Cassie discovers a message from her mother in an old leather-bound book of spells hidden in her mother's childhood bedroom, that she understands her true and dangerous destiny. What Cassie and the others don't yet know is that darker powers are at play, powers that might be linked to the adults in the town, including Diana's father and Faye's mother - and that Cassie's mother's death might not have been an accident. But the more time passes by, the more Cassie gets confident of herself and develops her incredible potential.

Cassie is a member of the Blake family, and the Blackwell family.

Early life

Cassie Blake was born on March 28, 1995 to Amelia Blake and John Blackwell. Shortly before Cassie's birth, John betrayed Amelia by having an affair with Elizabeth Meade which resulted in her half-sister Diana Meade being born less than a month later. John also summoned demons which resulted in Amelia leaving him prior to the events of the Boatyard Fire. Sara Armstrong stated in the Witness flashback that Amelia would never forgive John for what he did to her and that Amelia helped Ethan in the plot to kill John which backfired and led to the death of hal the members of the Circle. Later consumed by guilt and stripped of her magic, Amelia abandoned what was left her coven by moving to Los Angeles with Cassie. Amelia had to keep witchcraft and Cassie's magic legacy along with the truth about her father a secret from her daughter prior to her death in Pilot.

Season One

Main Article: Cassie Blake/Season One


Despite Cassie's independent and strong-willed personality, she is a very kind and loving young woman who cares deeply about her family and friends. When she uses dark magic she is seen with an evil look in her eyes.

At any rate, it seems grief mold her personality in more ways than one. First her mother died and the loss, along with the realization she will have to start doing things on her own, made her tougher. Then her grandmother died and she channeled all the anger she felt against the witch hunters.  Her use of Dark Magic also began to take a hold on her, making her more short-temperd and more willing to kill then to listen to both sides.

Physical Appearance

Cassie Blake is well-known for her beautifully long blonde hair, heart-shaped face, full lips and ocean-blue eyes. She's petite and not very tall, standing at 5' 2½. At the beginning of the series she wore more colorful clothing but as her dark magic was revealed she slowly began wearing more grey and black clothing.

Powers and Abilities

Cassie is one of the most powerful witches we have seen to date. What she lacks in formal magical training she makes up for it with raw power.

Cassie using Photokinesis

Her great potential was shown early in the series when she managed to subdue a storm neither Faye or Diana could stop, showing an affinity for Atmokinesis. When the entire Circle was once kidnapped and was about to be killed by Luke she was able to blow up one of Luke's Witch Cruids with a solid shout. Seconds after this, she reversed the effects of the Witch Cruid, causing it to set Luke of fire ,killing him instead of Diana, proving just how powerful her dark magic truly is as she activated its power through instinct alone and it was enough to overpower a barrier of ashwood, a special type of wood which renders most use of magic useless, thought it may not work on Dark Magic, as Iron, which blocks normal magic, did not seem to effect it.

When Faye was being contacted directly by the residual energy of her dead grandfather, Cassie was the only one who could see the ilusions as well, indicating she has stronger magical senses than Jake, Adam, Diana. When Isaac tried to kidnap Cassie and deliver her to the council of Witch Hunters, he recognized the danger she poses on them shall her dark magic been unleashed on the boat and so he didn't pursue her when she escaped.

When Kate Meade buried her alive to test the limits of her powers by bringing her to the brink of death, Cassie's dark magic proved to be too powerful for the ritual to hold her and such it was proven that she is more powerful than an experienced Elder.

At the Fire and Ice Dance, Cassie proved to be highly resistant to external influences that seek to take away her powers, as shown when the Voodoo ritual Faye and Lee made failed to overpower her natural defenses. This ability was shown again when a potion with Lethe root designed to take away her feelings for Adam didn't work on her.


Cassie using her Dark Magic to create flames

During Sacrifice, she fought against a demon and although she failed to defeat it she succeded in employing the use of Pyrokinesis. Cassie also repeatedly shows outstanding use of Telekinesis ranging from lifting heavy things and throw them to light weighted spears with greater precision. She also has considerable constrictive powers, as shown constantly when she have choke someone with dark magic. During Family, she succeded in overriding the command John Blackwell put on the Crystal Skull and used it to kill her father, albeit with the help of her sister Diana.

Cassie have also used Circle magic to great effect like when they toss around Zachary Larson with Aerokinesis and when she combined her powers with Jake to fend off witch hunter Simone. Apparently, she also has great potential to use Photokinesis, as displayed in Bound.

While her half-sister Diana also has Dark magic, Cassie has a stronger magical potential because she is also a Blake. In fact, if she would have the same amount of magical training as that of John Blackwell, it would be fairly possible that Cassie would be more powerful than Blackwell, but as she lacks years of training her father is still more powerful than her through experience. That was proven when Cassie couldn't kill the demon possessing Samuel despite exploiting a demon's weakness while Blackwell completely destroyed it

It is possible that Cassie is the most powerful witch in her circle, due to both her Blake and Blackwell bloodlines.
