How to Use Worldbuilding to Deepen Your Plot

October 11, 2021

Worldbuilding and plotting are two separate processes, right?


Wrong. Like every component of fiction, story world and plot are interlinked. Or rather, they can be. When you make the effort to use worldbuilding to deepen your plot, your book will feel intentional and whole. Otherwise, worldbuilding can seem extraneous. To mesh world with plot, you must start by understanding the heart of your fictional universe.


The Heart of Your Story World

In many successful story worlds, a main worldbuilding element or guiding principle affects nearly everything and everyone in the story. It’s one of the central differences between the story world and the real one. The concept of a guiding principle can be found in our worldbuilding questionnaire in the resource library. A guiding principle is a unique facet of your world that changes every (or nearly every) aspect of the world. Examples include the Rings of power in Lord of the Rings and dragons in How to Train Your Dragon, which not only distinguish these worlds from our own but also radically shape the plot.


A guiding principle can originate from two places: your planet’s creation or an event that transformed the world’s makeup. The first can take the form of abnormal laws of nature or a magic/power system. The second is often an unnatural addition that altered the globe, like an apocalyptic disaster or the introduction of new technology. Either origin can work as long as you know what route you’re choosing.


Before you decide how your guiding principle influences the plot, however, you must establish what your plot looks like.


Two Types of Plots

Most stories (especially ones with high stakes) tend to follow a preventative plot line or a reversal plot line where the protagonist is striving to either thwart or undo a catastrophe. In a preventative story, heroes attempt to ward off a looming disaster, like the Avengers trying to stop Thanos from collecting and using the Infinity Stones in Infinity War. In a reversal plot line, characters counteract preexisting circumstances, like overthrowing an evil government or group of scientists in every dystopian trilogy ever.


Though these two types of plots abound in high-stakes fiction, they’re not the only way to structure a story. Ultimately, the story line is determined by your protagonist’s and side characters’ goals. But evaluating these two primary plots will provide a starting point from which to connect the plot and your story world’s main element.


Integrating Story World with Plot

To fuse worldbuilding with plot, all you need to do is discover an inherent problem in your story world’s guiding principle. This problem might originate from creation or be caused by mankind’s hand. Perhaps a scientist has released a virus that must be cured before the population perishes. Maybe an antagonist has learned how to manipulate magic for evil and must be stopped from wreaking havoc. The problem’s solution will become part of your protagonist’s objective, which impacts the overall plot.


In Marvel’s Spiderman: Homecoming, the existence of superheroes and aliens is the core of the story world. A problem arises when leftovers from alien and superhero battles are recovered by the film’s villain, who uses the technology to build high-tech weapons he sells to criminals. The conflict springs from that world’s main worldbuilding element.


Guiding principles can direct subplots as well. Although one of the main plots in How to Train Your Dragon deals with destroying the dragon’s nest and driving the creatures away, the chief subplot revolves around Hiccup’s dragon training with Gobber and the island’s teens. Since dragon fighting is commonplace in the Viking world, having a training program for youngsters is only logical. Hiccup’s actions in the ring color every important relationship and subplot in the film, including his interaction with his future girlfriend and his father. The smaller implications of the overarching problem generate and steer its subplots.


Make sure each character holds a belief regarding the main problem. Characters’ different stances can greatly affect subplots. Pivotal turning points in Hiccup’s relationship with his father and Astrid hinge upon their views concerning the story world’s main problems.


Relating subplots to your story world’s heart isn’t required, but it helps readers feel immersed in the fictional universe. It reaches into the protagonist’s everyday life because he must wrestle with micro manifestations of the larger issue.


The Perks

A benefit of tying plots to a guiding principle is that the protagonist must heavily interact with, or even master, that portion of the story world. If he doesn’t, he won’t have a solid grasp of the problem or the solution. In Kung Fu Panda, Po must master the art of Kung Fu to stop Tai, the villain. In How to Train Your Dragon, Hiccup must tame dragons to show his village their peaceful nature and eventually defeat a larger, maleficent dragon.


This helps you avoid unnecessary info dumps. Since your story world’s magic system or other anomalies are no longer extraneous, details about the world seem necessary—and even interesting and pertinent. Revolving the plot around the problem inside your story world’s central element gives the protagonist a reason to understand it, familiarizing readers with the world.


See? Plotting and worldbuilding aren’t independent after all. With a little effort, you can create a guiding principle that not only influences your plot but is your plot. The two processes become inseparable in a complementary relationship that readers can lose themselves in.

    SO COOL!
    I love a good story, and world building is a huge part of it for me. I think that the challenge for me is just allowing the world to come out in the writing (“unnecessary info dumps”) where it would otherwise be more directly linked to the desire line. But I so love those stories where the world really shines, like Lord of the Rings, Chronicles of Narnia, and a more recent series called the Five Kingdoms by Brandon Mull. A good story world is so inspiring.

    I think the best thing for me though is when its a believable world – like an extension or slight tweak off of our world. That’s why LotR is so good, because the world is familiar enough to be believable and strange enough to be interesting.

    Thanks Gabrielle! Great article!

    That’s a challenge for me too! I want to make sure readers understand, so I end up shoving too much at them all at once, confusing them.

    Those type of worlds are pretty cool :).

    Thanks for reading!

    Wow! This is really well sparsed out, and I think it’ll help me with my WIP.

    I love this! I’ve created two guiding principles for my own trilogy and the world is so much richer and interesting. Now I’m working on a document so I can delve deeper into the worldbuilding. I could not have done it without hearing about this.
