The Darkhold is a hazardous book, and as seen in Doctor Strange in the Multiverse of Madness, it corrupts not just anything it comes into contact with, but also the reader from within, bringing out the worst in anyone who uses it.
It comes out that there are several copies across the many realities, with the primary one being at the temple of Chthon, where its origins are described.
Warning! Spoiler alerts!
Wanda gets obsessed with doing whatever she can to be with her children, Billy and Tommy, in Doctor Strange in the Multiverse of Madness, to the point where she is ready to take America Chavez‘s powers and maybe take the teen’s life in the process.
In the end, Wanda recognized that it was the Darkhold who had corrupted her to the core, forcing her to do evil things and turning her into a monster from a hero. She chooses the high road and resolves to demolish the temple of Chthon, which has all of the Darkhold‘s original writings on its walls, ultimately choosing the right path.
The Darkhold is claimed to have come from the Dark Dimension, which is said to hold endless knowledge about the cosmos. Because the book is comprised of Dark matter, it is a reliable source of Dark magic. Those who get the Darkhold are supposed to either be doomed or become one of the most powerful creatures with a limitless reservoir of knowledge.
The Darkhold is a book of spells in which the reader can follow the directions and have their wishes granted. Its language is personalized to the reader, making it only understandable by the bearer. The Darkhold has the key to energy generation and harnessing. The book has the ability to poison the reader’s psyche.
The Darkhold is run by Chthon, an ancient evil creature, and the temple where they visited is where he was laid to rest, as Wong recounted to Wanda. The guardians of the area, on the other hand, bowed down to Wanda, probably believing she had been eaten by the Darkhold and therefore siding with Chthon.
This implies that Chthon might still appear in the MCU at any time and pose a significant threat, but with Wanda learning what to do and when to do it, the evil will undoubtedly have someone who has experienced the worst from the Darkhold to stop the demon once and forever.
