Warning! Spoilers ahead for Doctor Strange in the Multiverse of Madness.,Doctor Strange in the Multiverse of Madness brought about a swift end to some powerful artifacts of the MCU. The Darkhold, also known as the Book of the Damned, and its polar opposite, the newly introduced Book of Vishanti, were both destroyed by Wanda Maximoff, a.ka. the Scarlet Witch. While the Darkhold had a more definitive end, the fate of the Book of Vishanti was much more ambiguous, and a key Infinity Stone mystery from Doctor Strange’s first MCU appearance can easily retcon the ending of
Doctor Strange 2.,In the sequel, the former Sorcerer Supreme is introduced to fledgling superhero America Chavez, who has the power to traverse the multiverse. He must protect her from the Darkhold-corrupted Wanda, who looks to take America’s powers for herself. Doctor Strange and America travel through different universes looking for the Book of Vishanti, which can give him the power to stand against Wanda and the Darkhold. However, Wanda follows Doctor Strange and America to the Junction of Worlds by dreamwalking and blasts the Book of Vishanti before nabbing America and sending Doctor Strange to yet another universe. While it is heavily damaged by Wanda’s magic, though, the Book of Vishanti’s end is not as definitively shown as when Wanda topples Mount Wundagore and destroys every copy of the Darkhold across the multiverse.,Related: Did Marvel Really Just Kill Off That Important Doctor Strange Character?,The Book of Vishanti is powerful in its own right, and there’s a chance it could have survived the assault of Chaos Magic. However, a big Infinity Stone mystery dating back to 2016’s 
Doctor Strange can simply retcon the destruction of the Book of Vishanti. Originally intended to hold the Time Stone, the Eye of Agamotto is an artifact that Doctor Strange makes use of early on as the Sorcerer Supreme. He continues to wear the Eye in
Doctor Strange and the Multiverse of Madness even after the Time Stone was removed from it during the events of 
Avengers: Infinity War. The Eye itself is a big mystery in the MCU as it is the only reference to Agamotto, the first Sorcerer Supreme and one of the three Vishanti. Not much is known about Agamotto and how he got the Time Stone, but the very existence of Agamotto in the MCU sets up a key retcon so that the Book of Vishanti and its spells are not completely lost.,Doctor Strange 2 has some surprising
 developments about the Darkhold that may also apply to the Book of Vishanti. The biggest of these is the fact that the Darkhold is a copy of all the spells etched into the walls of Mount Wundagore by the first demon, Chthon. If the Book of Vishanti has a copy or is itself a copy of something else, Agamotto would be the first to know.,Doctor Strange 2 is full of shocking twists like America Chavez’s full powers and Doctor Strange’s new third eye. But if the Darkhold and the Book of Vishanti have truly been destroyed, then Doctor Strange has lost some powerful tools that could be of use in the future. With the post credits scene of 
Doctor Strange in the Multiverse of Madness revealing Charlize Theron’s Clea and the return of the Dark Dimension, the Master of the Mystic Arts is sure to have a grueling battle ahead.,Next: Everything We Know About Doctor Strange 3
