Doctor Strange in the Multiverse of Madness Debuts The Book of Vishanti

Sam Raimi was not lying when he said that the Doctor Strange sequel project would really push beyond the boundaries of the Marvel Cinematic Universe. As the Scarlet Witch lays waste to Earth-838 and its Illuminati, Doctor Strange and America Chavez make it to the Gap Junction. The Gap Junction – the “space between universes” was the seat of the Book of Vishanti, the single greatest, most powerful collection of ancient white order, Eldritch magic in the universe.

The Book of Vishanti was so potent that it was using its power that the Illuminati managed to defeat the Thanos of their reality. It couldn’t save Earth-838’s Doctor Strange from bring corrupted though. The Doctor Strange of their universe willingly submitted to sacrifice his life, lest the corruption turn him into a bad guy. While any weapon of absolute power corrupts absolutely, we wouldn’t hold why the Book of Vishanti not being able to save Doctor Strange of Earth-838 against it.

What did catch our attention is the fact that the Illuminati didn’t use Pym Particles to travel across time to undo Thanos’ actions. All they did was use the Book of Vishanti to do in a fairly short while what took the Avengers of Earth-616 years to do – beat the Infinity Gauntlet.
Why The Book Of Vishanti Is So Powerful

The primary reason the Book of Vishanti is held in high regard is because it was the polar antithesis of the Darkhold. Both granted its wielder a tremendous amount of magical potential but the corruption was probably less severe with the Book of Vishanti. It can destroy whole realities, killing trillions of civilizations by initiating an incursion. And like the Infinity Gauntlet, it does not leave lasting bodily damage. If the Darkhold is of any indication, the Book of Vishanti (which holds similar power) can do wonders that defy even the limits of the Infinity Gauntlet.
The Book of Vishanti – EXPLAINED

An ancient book of spells of white order magic, the Book of Vishanti contains the combined knowledge of the Vishanti. The Vishanti are a trio of magical entities that have pioneered the arcane and have ascended to a higher plane of existence. Oshtur – an Elder Goddess, Hoggoth – the last survivor of a powerful alien pantheon, and Agamotto – humanity’s first sorcerer. Together as the mystical trinity of the Vishanti, the trio dictated the Book of Vishanti to its first human authors.

The magician Varnae was the first wielder of the Book of Vishanti in the comic books. Using the power the book and the Darkhold granted, Varnae became the world’s first vampire. The book of Vishanti has exchanged hands many times. The last time it was seen in the comic books, it was used by Doctor Strange to cast the spell of Tartashi. It helped the New Avengers in finding out Skrull impostors among their ranks during the events of Secret Wars.
Will It Come Back To MCU?

The Scarlet Witch seemingly destroyed the Book of Vishanti in the Gap Junction. But since this is the Multiverse, the Book of Vishanti could return back to the MCU. Doctor Strange in the Multiverse of Madness reveals that every universe has their own version of the Darkhold. Since the Book of Vishanti is the antithesis of the Darkhold, every universe within the multiverse houses its own separate Book of Vishanti as well.
