When we began working to create the Accursed setting, the creative team quickly came to the decision that we needed to have a lot of horrific elements. Part of that was because we knew that the Witches were going to be extraordinarily powerful beings that wouldn't be a good fit for routine opponents. Another justification was simply due to the fact that we needed things that would give a prototypical monster pause. After all, a Dhampir, a Mummy, or a Revenant is unlikely to find even a force of mundane humans threatening. Our solution was to expand the scope of what the Witches had done.

In appearance, the Morrigan’s form is quite memorable—her hair is a dark, earthy brown in color, her eyes a gleaming ice-blue. Her complexion is flawless, and her willowy form is considered quite beautiful, if somewhat ethereal. Her attitude did not change much between her guise as “Lady Macha” and assuming her mantle as the Morrigan. She is quick to anger, slow to forgive, and coldly intelligent. She is the complete mistress of all cauldron-born, and even the most willful of undead bow their heads to her commands. Only the Revenants have broken free from her dominance, and as a whole, they have sworn to oppose her with every ember of their being.

The Chimera makes her home in a massive, spired fortress known as Turris Atra. Unlike other fortresses, however, the Chimera’s home does not long remain in any one place. With each dawn, the inhabitants of Morden discover Turris Atra and its surroundings in a new locale. Though it only stays until the following midnight, the Witch’s fortress invariably spreads sorrow and grievous loss before it departs. The Chimera is the tower's mistress. Whenever she visits a new site, she promptly abandons her completed experiments and begins gathering up the living components to begin anew. Any nearby life could potentially be drawn into her next project—to their eternal dismay.

The Crone is the first Witch, Mistress of the Grand Coven, and oldest among her sisters. Legends say that at the dawn of time, she was the first mortal woman to take on the mantle of the Immortal Witch. If this is true, she is the mold from which all other Witches are struck. It was the Crone who brought such disparate and stong-willed individuals as the Djinn and the Morrigan and the witch now known as Baba Yaga together to form the Grand Coven. It was she who laid the plans for the invasion of Morden. Through the sheer force of her will, she directed the advance of the squabbling, largely incompatible Witch Armies.

The Djinn's current status remains one of the greatest mysteries of Morden. When King Auberon's blade pierced her flesh, she vanished, taking much of her army, the forces of the Alliance, and even the Summerlands with her in a cataclysmic magical explosion. No human scholars know her ultimate fate, and even the Witches seemed unnerved by this dramatic turn of events. Though the Witch armies had essentially won the war, many of them left Morden with their armies, crossing the Darkfall Peaks to their homes that lay beyond.

They came through the Outlands, boiling over the Darkwall Peaks in their multitude. Huge throngs of undead things and living creatures twisted beyond recognition by dark magics. Rank upon rank of hired soldiers from across the great sea bolstered their numbers. In the van were the Accursed–shambling Mongrels, plodding Golems, loping, gibbering Vargr, lithesome Damphyre, along with their fellows. At their head strode the great usurpers, the Witches of the Grand Coven. Cunning Baba Yaga, mighty Sanguinara, the twisted Chimera, and their sisters led their varied armies over the Darkwall Peaks and into the unsuspecting lands of Morden quick as lightning, taking the unprepared mortals completely unawares and easily sweeping aside the initial, hastily assembled resistance. The Witch armies spread out and the heroes of the Alliance gathered their armies to oppose them. The entrenched forces settled in for a savage war of attrition that would grind on for decades and only really end with the Great Betrayal, when the Grand Coven was broken and the Witch armies scattered to the winds.
