|“||Bring him down, sisters!||„|
|~ A Brigmore Witch while attacking Daud|
Similar to the Whalers, each witch receives her power from the leader of the coven, Delilah, who has been granted her powers by the Outsider. The witches are able to teleport, unleash a scream which knocks the target backwards and can create and shoot shadow projectiles at their enemies.
The witches also use necromancy-like magic to protect their manor. They bewitch the skulls of dead dogs, causing them to reanimate when an enemy is nearby. The skeleton dogs get back up each time they are defeated until their skull is destroyed.
If the witches are not alerted to Daud's presence, their skin is normal coloured. However, during battle they turn into green, plant-like women. Despite Delilah's claim in The Knife of Dunwall, stating that she would prefer not to kill Daud for her sisters' sake - thus implying that the witches respect Daud, all witches are hostile in The Brigmore Witches.
Knife of Dunwall
During The Knife of Dunwall, only the coven's leader Delilah is encountered. Having turned Daud's second-in-commandant Billie Lurk against him, she amusedly watches how events unfold. She eventually reveals herself, threatening Daud not to seek for her anymore - elsewhise she would kill him.
The Brigmore Witches
Some Brigmore witches are encountered when Daud works for Nurse Trimble. Inside the sewers near the textile mill, Daud can hear a woman asking for help. She claims to be hurt and cannot get up without help. If Daud helps her, the woman reveals herself to be a Brigmore Witch and attacks Daud.
Another ambush is laid by other Brigmore Witches in the sewers. If Daud turns a wheel to open a gate, he can her voices whispering that someone is coming for them. If he continues this way, he is ambushed by three Brigmore Witches who attempt to kill him.
Most notably, the witches are encountered when Daud infiltrates Brigmore Manor to take down Delilah. Having been warned about Daud's arrival, the witches patrol the precinct to prevent him from finding Delilah. Daud can either fight them or sneak past them.
Eventually, Daud learns of Delilah's plan to possess Empress Emily Kaldwin to rule in her stead. Daud manages to follow Delilah into the void and defeats the witch.
After Delilah is defeated and her spirit is trapped in the Void, the Brigmore witches lose their magical powers. Most leave the coven and start a new life throughout the Empire. Twelve years after the events of Dishonored, Delilah's second-in-command Breanna hears a whisper from the void. After rousing up some loyal friends, Breanna managed to return Delilah from the Void. With Delilah, who has returned with even greater powers, the power of the witches returns. Delilah builds a new coven, partially from members of the old Brigmore crew, partially from new members flocking to Delilah.
Breanna, who had become the curator of Karnaca's Royal Conservatory, closed off the conservatory to the public, making it the new headquarter and place to live for the witches.
Three years later, Delilah, with help from the Duke of Serkonos, takes over Dunwall Tower and the Empire in a coup, forcing either Corvo Attano or Emily Kaldwin into exile. Dunwall Tower and the surrounding area is swiftly taken over by the witches who turn it into their new headquarter, dilapidating most of the original tower. They also start growing herbs and alchemical substances in a former garage. At one point, the High Overseer storms the Tower with his Overseers, intending to eliminate Delilah and the witches. Although the Overseers prove to be superior to the witches by using their magic-depowering music boxes, the Overseers are eventually slaughtered when Delilah unleashes her Clockwork Soldiers.
Meanwhile, in Karnaca, the witches that remained in the Conservatory - including Breanna - are either slaughtered or permanently depowered by the protagonist who has arrived in Karnaca to strip Delilah of her followers and power. Ultimately, the witches in Dunwall are eliminated as well when the protagonist comes back to confront Delilah. Even Delilah is defeated, allowing the protagonist to take back the throne and to save their remaining relative.
