Invoking the Moirai is a spell to invoke the Moirai, the three Greek goddesses of fate, to change "their grand design" and rewrite the past of the caster and an intended target, making it so that they never met. The spell requires the Power of Three to be effective.
Overview[]
This spell cannot be used to reverse someone's death, only chance encounters, relationships and life decisions. As altering time is an extremely powerful act of magic, the spell can only be achieved by the Charmed Ones through the Power of Three. However, the incantation does not require all three sisters and can be cast by two Charmed Ones as long as the sand symbol was formed by all three.
The spell works by changing the past, creating a new timeline in its place. Harry Greenwood noted that the spell was dangerous and could cause unforeseen consequences. For example, without Niko Hamada around to wake her up in this new timeline, Mel Vera realized that she must have slept through her alarm and missed the interview for her teaching position at Hilltowne University and thus never received the job.
A further side effect of casting this spell is that those present at its casting will retain their memories of the previous timeline, but will have no memory of events that happened to them in the new timeline if their life was changed as a consequence.
Another side effect is that the target of the spell will still retain a limited awareness of their original history, meaning they will feel something is missing and be drawn to certain places, but if they fully learn about the previous timeline, they will bleed from their eyes and nose while their mind tries to recall the erased memories.
History[]
After Niko Hamada was targeted for assassination by the demonic Shapeshifter, Hunter Caine, in "Other Women", the Vera-Vaughn Charmed Ones cast this spell at the urgency of Mel Vera in order to remove Niko Hamada from their lives and keep her safe from the demon. Mel was not required to be physically present while her sisters cast the spell nor to recite the words of the incantation, taking the time to say goodbye to Niko as Macy Vaughn and Maggie Vera completed the spell in the attic and history was rewritten.
Book of Shadows Entry[]

Book of Shadows entry
Invoking the Moirai
Objective: to untangle the fates of the
caster and the subject of the spell, preventing
their first meeting any subsequent interaction
between them.
Death cannot ever be reversed.
Altering time is a monumental
undertaking that requires the
Power of three. Be warned:
the lives of both caster and the subject
will be irrevocably changed in a
multitude of ways. Once complete,
the spell cannot be undone.
Materials: sage, candles and sand.
The Charmed Ones together must pour sand from
their hands into the shape of the mandala. Two or more
Charmed Ones must recite the following:
Incantation: We call upon the Morai —
Clotho, Lachesis and Atropos, daughters of the night
Rulers of fate We beseech thee
Sift and flow the sands of time to rework your grand design
diverge their paths
Not two, not one undoing that which was once one
Take what was, make it no more
Like sands swept away then back to shore.
We call upon the Moirai ~
Clotho, Lachesis and Atropos
daughters of the night
Rulers of fate
We beseech thee
Sift and flow
the Sands of time
to rework your
grand design
Now two, not one
Undoing that which was once done
Take what was, make it no more
Like sands swept away
then back to shore
While the Moirai are the rulers of fate
they cannot undo the work of their brother,
Thanatos, the god of death.
Trivia[]
- Powerful creatures that wield magic sense will be able to senses the use of powerful spells of this kind and determines their effect, but nobody (except those who participated in the ritual of invoking the goddesses) is going to be able to determine the specifics of the changes made.
- According to the Caines, only the Charmed Ones could have been powerful enough to pull off this kind of spell.
- Despite the rewriting of history, this spell cannot change death. It is currently unknown what happens with the deceased that might be directly involved with the altered history. In the new alternate timeline, they may have died under different circumstances, or the circumstances of deaths remain the same as in the original timeline, but adjust to new events.
- The spell states that the Moirai need to rework their grand design. In the original series, the Grand Design was a major theme in the later seasons, with the balance between good and evil needing to be maintained, and it was the duty of the Charmed Ones to help protect it, while the Angels of Destiny oversaw the Grand Design.
- The incantation on the first page of the Book of Shadows entry includes various misspellings and grammatical errors, while the incantation of the second page is correctly written.
- The power of Reality Warping allows users to change history in a similar way to this spell, but without most of its limitations, such as reversing death.
