Westview’s location could be key to WandaVision and the MCU’s Multiverse. After seven episodes, WandaVision is finally revealing its mysteries. Episode 7 formally introduced viewers to the main villain, Agatha Harkness, complete with an unforgettable song routine. It also featured an advertisement for something called “the Nexus,” an enigmatic clue that has a few possible meanings.
This is most likely a reference to the Nexus of All Realities, which in the comics is traditionally an area in the Florida Everglades where the fabric of spacetime is exceedingly threadbare. It is typically used as a gateway between alternate dimensions, but in reality it is far more; it serves a crucial purpose in maintaining the balance between realities, and misuse of the nexus risks damaging the structure of reality and causing a Multiversal collapse. Some comics, such as Quasar #50, have hinted there are actually countless entrances into the Nexus of All Realities, and they are all typically guarded by beings such as the Man-Thing. The Nexus of All Realities has already been teased in the MCU, referenced in Erik Selvig’s notes in Thor: The Dark World.
The MCU has always been careful to ground its mysticism in pseudoscience – Marvel even consulted with quantum physicists when deciding how magic should work in Doctor Strange – which means it’s intriguing to ask just how such a nexus would work in this particular shared universe. One possibility lies in the idea of ley lines.
The idea of ley lines was originally proposed by antiquarian Alfred Watkins in the 1920s, who noticed major landmarks across the world all fell into a sort of alignment, whether they were natural or man-made. It has since been refined and developed, and proponents now believe there are lines of mystical power that run across the globe, and that sorcerers and mystics can tap into these pockets of energy. A nexus would be a place where multiple ley lines converge, with their power amplified significantly at that point. Naturally ley lines have been referenced several times in the comics, usually by Doctor Strange himself, but they also feature prominently in David Annandale’s recently-published Marvel novel The Harrowing of Doom. There, Victor Von Doom learned to tap into such a nexus in order to perform remarkable feats – and actually attempt to plunder Hell.
It is possible Westview is situated on a nexus of ley lines, explaining why both Scarlet Witch and Agatha Harkness are so powerful there; they are drawing on a vast reservoir of mystical energy to rewrite reality. Indeed, the hexagonal shape of the Hex surrounding Westview may itself be a major clue, indicating six ley lines converge at Westview – with the center being the intersection between them. It’s important to remember that, in the MCU, magic is tied to the nature of reality itself; the Ancient One explained that sorcerers “harness energy drawn from other dimensions of the multiverse.” Thus you would naturally assume significant nexuses of ley lines are places where the fabric of reality was particularly thin and malleable. This psuedoscientific explanation works surprisingly well.
Ley lines may already have been implicitly referenced in Thor: The Dark World, which revealed there are points where the Nine Realms are close to one another and it is possible to slip between worlds without need of the Rainbow Bridge; these could be similar convergence points of ley lines. It is notable that several locations in these films are actually places where ley lines are claimed to intersect in the real world, including Greenwich (where Malekith attacked Earth in Thor: The Dark World) and even the town of Tønsberg, Norway. This is one of five locations sometimes claimed to sit on a “Norway Pentagon” of lines of spiritual power, and it is certainly interesting that Asgard has been tied to Tønsberg so many times – with the Asgardian refugees settling there in Avengers: Endgame.
This theory would fit well with Doctor Strange, in which Mordo revealed the Masters of the Mystic Arts were formed millennia ago to protect the Earth from interdimensional threats. He revealed their founder, Agamotto, built three Sanctum Sanctorums in places of power – perhaps places where multiple ley lines converge, meaning the fabric of reality is particularly thin and the power of sorcerers is amplified as a result. One is situated in Hong Kong, one in London, and the most famous – which now seems to be guarded by Stephen Strange himself – is in New York. The ley line theory would consequently account perfectly for how magic has been shown to operate in the MCU to date.
If this theory is correct, though, WandaVision could cause significant problems for the Masters of the Mystic Arts – simply because two powerful sorceresses are now drawing on a nexus at the same time. Annandale’s The Harrowing of Doom suggests overuse of a nexus can cause the ley lines to shift, with convergences either broken or shifting. Assuming this is true in the MCU as well, it’s possible the conflict between Wanda Maximoff and Agatha Harkness will have precisely that effect, as they draw upon too much mystical power fighting it out in the final episode. Such a shift could have an impact on the ley lines of North America – and even cause a minor movement of the nexus beneath the Sanctum Sanctorum. Imagine it moving just a little in a sort of mystical readjustment, shifting so it was exposed and perhaps even allowing traverse between dimensions; that would explain reports of three different iterations of Spider-Man in Spider-Man 3, as the various wall-crawlers unwittingly cross dimensions.
No doubt the Masters of the Mystic Arts would need to put matters right swiftly, realizing Earth was more vulnerable than ever before. Stephen Strange would inevitably find himself in a race against time, as he desperately attempted to find a way to repair the damage caused to reality itself even as other, predatory entities from the Multiverse attempted to invade the Earth. Thus WandaVision‘s ley lines could serve to set up the entire Multiversal thrust of Phase 4 – and force Doctor Strange to prove himself worthy of being Sorcerer Supreme.
