One part of Zenescope's Grimm Universe worth explaining on its own is the four Realms of Power: Myst, Wonderland, Neverland, and Oz. These places exist as other dimensions connected to Earth, which is called the Nexus. So when the books talk about the four realms, Earth is the connection between them rather than one of those four. The familiar names can be misleading if you're expecting the versions you grew up with. Myst Myst is the broader fairy-tale world, with its own kingdoms, magic, and conflicts. Robyn Locksley's trip to Nottingham happens here, and Sela has deep ties to the realm. It gives the Grimm Universe room to bring different legends into the same setting without having to fit everything into Wonderland or Oz. Wonderland This is the realm of dreams turned into something dangerous and unstable. The Liddle family is at the center of a lot of its stories, and escaping Wonderland doesn't necessarily mean you've escaped what it does to you. Calie and Violet have to deal with its influence reaching into their lives on Earth. The horror follows them home. Neverland The original Neverland story makes Pan's refusal to grow up a pretty horrible thing. His immortality depends on children, and the place he rules has become a nightmare. Hook gets a very different role here too, as someone who escaped as a child and may be able to stop him as an adult. That changes the whole relationship before you even get into the later stories. Oz Dorothy, witches, and the struggle over Oz are all here, but this version leans into dark fantasy and conflict over who controls the realm. Dorothy and her allies have a lot more to deal with than finding a way home. Stories like Warlord of Oz build on that, with the land facing new threats even after an earlier enemy has been defeated. Earth being the Nexus is what brings all of this together. Someone can be dealing with a monster in a modern city while another book follows a conflict in one of the realms. Eventually, those problems can become everybody's problem. That's where characters like Sela and Skye come in as Guardians. There are other places and realities in the comics too. These four are the basic layout to have in mind when getting into the Grimm Universe. I'll get into the individual realms and their characters more as I work through the books.
