Have a magic system in mind for your fantasy world? Here's a list of things to consider to help you tie this system into the rest of your worldbuilding, so that it feels more believable and realistic.

Source

What is the source of magic? Is it natural or man-made? Can humans use magic or is it a force of nature that only animals or other races can use?

Does magic originate from inside a person or does it require external items to use? If it comes from items, can the items be made? How long does it take to make the items?

Does the magic cost anything- money, stamina, health, etc.?

Can a person be cut off from being able to use magic? If so, how?

Prevalence

How common is magic in your world? Is it so common that everyone has seen it or is it a subject of myths and rumors?

How long have the people in your world known about magic? Has it always been there or is it a new discovery?

How much does the average person know about magic? How much do experts know? What do people not understand about this magic? Are there any common misconceptions? Myths?

Is magic revered or feared? Or if it's common, is it taken for granted? Are there any taboos surrounding magic?

How many types of magic are there? Are some more common than others?

Are there dedicated schools of thought surrounding the study of magic? Is it taught about in schools? If so, is it taught to children or only at the college (or equivalent) level?

Accessibility

Who can use magic? Who can't? Is it something that only the rich and powerful can use? Why? Or do genetics determine who can use it? Wealth?

Are there any physical limitations that might restrict who can use magic? For instance, maybe old or sickly people can't use magic because it requires a lot of physical effort. Does your society provide accommodations for people who can't use magic? Is a lack of magic ability considered a disability?

Does education level determine capacity for magic?

How easy is it to gain access to magic? How easy is it to learn about magic?

Power/Usefulness

How powerful or useful is magic for different parts of society? Military? Medicine? Entertainment? Art? Childcare? Government? Communication? Business?

How does magic affect the politics of your world? How does it shape the economy? Are there feuds over the use of magic? Do powerful groups in your world have an incentive to limit the use and accessibility of magic? Why?

What happens when people no longer have access to magic? Does this cripple their ability to go through their daily lives? How?

Mix, match, and cross-reference these with other elements of your worldbuilding to form a believable magic system that lives and breaths just as the rest of your world does. For every answer you give to the questions above, consider and build upon the implications of what that might mean for your world. A worldbuilder's best skill is the ability to ask "How will this affect ___?" So make sure you're always considering the ripple effects of each element you add to your world.

Government & authority:

Types of government: What type of government exists (monarchy, democracy, theocracy, etc.)? Is it centralised or decentralised?

Leadership: Who holds power and how is it acquired (inheritance, election, divine right, conquest)?

Economy & trade:

Currency: What is used as currency? Is it standardised?

Freedom of religion: Are citizens free to practice different religions? If not, which are taboo?

Holy laws: Are there laws based on religious texts or teachings?

War & peace: What are the laws regarding war, peace treaties, and diplomacy?

Weapons: Are there restrictions or laws regarding weapons for civilians? What is used as a weapon? Who has access to them?

Technology & magic:

Technological advancements: How advanced is the technology (medieval, steampunk, futuristic, etc.)?

Magical laws: Are there regulations on the use of magic, magical creatures, or artifacts?

Innovation & research: How are inventors and researchers treated? Are there laws protecting intellectual property?

Environmental/resource management:

Natural resources: How are resources like water, minerals, and forests managed and protected, if at all?

Environmental laws: Are there protections for the environment? How are they enforced? Are there consequences for violations?

Cultural & ethical considerations:

Cultural diversity: How does the law accommodate or suppress cultural diversity?

Ethics: What are the ethical foundations of the laws? Are there philosophical or moral principles that underpin them?

Traditions vs. change: Does the society balance tradition with progress? How?

Happy writing ❤

Have you ever started writing a story and realized your world has a bunch of unexplained shit and you have to fill in the gaps as you go? Me too, buddy. Me too. Here’s a checklist so that you can fully flesh out your world to the max. (I’m dying)

Species (if Fantasy. Will probably make another post on this.)

Countries, Nations, Tribes, ect. (nationalities/ races. Will probably make another post on this.)

The geography of the world (draw a map. Doesnt have to be good. Just for a general idea.)

Rivalries between races (includes prejudice, racism, ect.)

Religions

Technology

The Magic system. (Will probably make a whole other post on this.)

animals, plants, ect.

The sky: Sun, Moon(s), Stars, Constellation, Are there rings? (If the planet has rings)

Educations system

Government system

Politics

Methods of transport (Vehicles)

Medicine

Here are a handful of quick tips to help you write believable characters! 

1. A character’s arc doesn’t need to grow linearly. Your protagonist doesn’t have to go from being weak to strong, shy to confident, or novice to professional in one straight line. It’s more realistic if they mess up their progress on the way and even decline a bit before reaching their goal.

2. Their past affects their present. Make their backstory matter by having their past events shape them into who they are. Growing up with strict parents might lead to a sneaky character, and a bad car accident might leave them fearful of driving.

3. Give reoccurring side characters something that makes them easily recognizable. This could be a scar, a unique hairstyle, an accent, or a location they’re always found at, etc.

4. Make sure their dialogue matches their personality. To make your characters more believable in conversation, give them speech patterns. Does the shy character mumble too low for anyone to ever hear, does the nervous one pace around and make everyone else on edge? 

5. Make your characters unpredictable. Real people do unexpected things all the time, and this can make life more exciting. The strict, straight-A student who decides to drink at a party. The pristine princess who likes to visit the muddy farm animals. When character’s decide to do things spontaneously or in the heat of the moment, it can create amazing twists and turns.

6. Give even your minor character’s a motive. This isn’t to say that all your characters need deep, intricate motives. However, every character should need or want something, and their actions should reflect that. What’s the motive behind a side character who follows your protagonist on their adventure? Perhaps they’ve always had dreams of leaving their small village or they want to protect your protagonist because of secret feelings.

- you don't have to write sex scenes. Tolkien didn't

- you don't have to write romance. Lewis didn't

- you can write very close friendships that have nothing romantic nor sexual in them. Scott Lynch did

- you can write sexual relationships that don't involve romance. Sapkowski did

- you can write romantic relationships that don't involve sex. Pratchett and Gaiman did

1. Where It All Started: The Character’s Origin

Place of Birth: Where did your character first see the world? Think about the impact of this place—was it a busy city where they had to fight for attention or a quiet village where everyone knew everyone’s business? This location doesn’t just say where they’re from; it shapes how they see the world.

Family and Upbringing: What was their family like? Were their parents loving or distant? Maybe they were raised by someone other than their parents—a mentor, an older sibling, or even alone. Family (or the lack of it) is usually one of the most significant factors in shaping who someone becomes.

Society’s Expectations: What was expected of them when they were young? Possibly, they were born into wealth, with all the pressure to continue the family legacy, or maybe they were raised to be invisible in a world where survival mattered. How does this influence who they are now? Do they accept or reject those expectations?

2. Childhood Events That Left a Mark

First Taste of Conflict: Think about the first time the character realized the world wasn’t a perfect place. Maybe they witnessed violence or faced betrayal. What was that moment, and how did it stick with them? This moment usually lays the foundation for the character’s emotional landscape—fear, hope, ambition, or distrust all come from these early life lessons.

Childhood Dreams: When they were young, what did they want to be? Every child has dreams—did they want to be a knight, a scholar, or even just someone who could travel the world? Did they have to give up these dreams? How does that lost dream shape them now?

Formative Relationships: Who was their first best friend, mentor, or enemy? Childhood friendships and relationships often create deep bonds or wounds that last into adulthood. Did they have a mentor who taught them everything, only to betray them? Did they lose a childhood friend that still haunts them?

3. The Teen Years: Where They Start to Become Who They Are

Trials and Tribulations: What’s the biggest challenge they faced as they grew up? Was it losing a loved one, failing at something important, or maybe being forced into a role they didn’t want? These teenage years are where the emotional armor starts forming—how did the difficulties they faced shape them into the person they are now?

Education or Training: How did they learn what they know? Were they formally trained by an institution, learning everything by the book, or did they learn through experience, like a street-smart survivalist? What impact does their education or lack of it have on how they interact with others?

Teenage Bonds: Did they have a first love or a first major falling out with someone close to them? These experiences often create emotional scars or connections that they carry with them into adulthood. How does that past friendship or romance influence their behavior now?

4. Key Life Events: The Big Moments That Define Them

Trauma or Loss: Was there a moment that changed everything? Think about a significant loss—maybe a loved one, their home, or a sense of identity. How does this event affect their worldview? Do they build walls around themselves or dive into relationships with reckless abandon because they fear losing more?

Victory or Failure: Did they experience a moment of triumph or devastating defeat? Success and failure leave their marks. Were they celebrated as a hero once, leading them to overconfidence, or did they fail when everyone was counting on them, leading to crippling self-doubt?

Betrayal: Was there a betrayal that shaped their adult relationships? Whether it is a friend, family member, or lover, betrayal often changes how we trust others. Do they close themselves off, constantly expecting betrayal, or try to rebuild trust, afraid of being left alone again.

5. Where They Stand Now: The Present Moment

What Drives Them Today: What’s the one thing pushing them forward now? Is it revenge, the need to restore their family’s honor, or maybe even just survival? Whatever it is, this motivation should tie directly back to their experiences.

Emotional Baggage: What unresolved emotional wounds are they carrying? Everyone has scars from their past—some are visible, others not so much. How do these emotional wounds affect how they treat others, how they react to conflict, and how they move through the world.

Current Relationships: Who’s still in their life from their past, and how do they feel about it? Did they reconnect with someone they thought they’d lost, or are they haunted by unresolved issues with people from their past? Do they have any ongoing tensions or regrets tied to these people?

6. Tying Themes to Their Backstory

Cultural or Mythological Influence: How does their personal story tie into the larger world’s mythology or culture? Do they carry a family legacy, a curse, or a prophecy that hangs over them? How does this influence their interactions with others and their perception of themselves?

Recurring Symbols: Are there objects, dreams, or people that keep showing up in their life, symbolizing their journey? Perhaps a recurring nightmare haunts them, or they carry an object from their past that’s both a source of comfort and pain

7. Character Arc: The Journey from Past to Present

How Does Their Past Shape Their Growth?: Every character has emotional baggage that needs resolving. How does their backstory drive their arc? Do they need to forgive themselves, let go of the past, or accept who they’ve become to move forward?

I made a HUGE mistake while writing my fantasy novel "The Sorcerer's Apprentice," thinking the antagonist Valeriano was the protagonist. Eventually, I realised the story didn't work because Altaluna, Valeriano's apprentice (who was originally a side character), was the true protagonist. Now, the novel is undergoing an enormous rewrite. So, yeah, here's the tip I wish I'd known sooner 😅

Hope this helps! If it does, do tag me or send me a link to your writing. I'd love to read your work.

But what about a different perspective.

What if the Sun was loud, unyielding, spiteful.

The Sun would blind their enemies, not care the damage they make, or the burns they leave behind.

What if the Sun was devastating.

What if the Moon was silent, gentle, cautious.

The Moon saw things from a different perspective, was a place of consistency in the darkness, collected friends like stars in the sky.

What if the Moon was optimistic.

What if the Moon took on the wrath of the Sun, and used it for safety rather than destruction.

When it comes to writing, one of the most exciting and challenging aspects is creating compelling characters. Whether you're penning a thrilling mystery, a heartwarming romance, a gripping fantasy, or a thought-provoking literary novel, the characters you bring to life play a pivotal role in captivating your readers. However, not all characters are created equal, and tailoring their personalities to fit the specific requirements of your chosen genre is essential for a successful and engaging story.

So, how can you ensure that your characters shine in the context of their genre? Let's embark on an insightful journey into the art of character development across different literary landscapes.

The Foundation of Genre-Specific Characters

Before delving into the intricacies of character development, it's crucial to understand that each genre comes with its own set of expectations and conventions. While a hard-boiled detective might thrive in a gritty crime thriller, they might feel out of place in a whimsical fantasy world. Therefore, the first step in crafting genre-specific characters is immersing yourself in the nuances and tone of the genre itself.

For instance, in a fast-paced action-adventure novel, the protagonist is often characterized by their resourcefulness, courage, and determination in the face of danger. On the other hand, a character in a cozy mystery may possess a keen eye for detail, a sharp wit, and a knack for uncovering secrets amidst the charm of a small town. By understanding the core elements of the genre, you can lay a sturdy foundation for building characters that resonate with the expectations of your readers.

Investigating Character Traits Across Genres

Let's take a closer look at how character traits can be tailored to suit different genres:

1. Adventure/Thriller:

Courage and Resilience: Characters in this genre often face high-stakes challenges and adrenaline-pumping situations. Their ability to confront danger with courage and resilience is a defining trait.

Quick Thinking: Whether escaping a treacherous trap or outsmarting a cunning adversary, characters in adventure and thriller novels are often marked by their ability to think on their feet.

similes for describing characters and their behaviors 🗡️ character inspiration

like the sun, radiant and raging against the far horizon, a clear beacon for others to follow

like a panther in the night, patiently stalking its unsuspecting prey

like a trapped bird flitting about, calling out for any help while nipping the hands that try

like a staircase in the woods, worn away by time, building up to something—somewhere—that not even you know

like a tree felled in a creek, uprooted from your home but still holding up to those who walk over you

like the static on old TVs, ever-present and ever-moving, fading to the background

like a cabin in a snowstorm, a comforting mirage as the world clutches me to its icy heart

like the antique vanity resting in the corner, stable in the dizzying array of things that come and go

like a stained glass window, taking the light you see in others and showing them all the colors within

like the glint of a knife, only there when you look from the right perspective

like a cat lounging in a garden, at peace with watching the world pass on

like reflections in a pond, serene yet obscuring what lies below

like a wound that won’t heal, annoying and a reminder of what happened

like syrup wafting through the air, sweet with a touch of familiarity

like the air after rain, fresh with the stench of earth and dew

like my favorite song, an unmistakable tune of nostalgia and hope to dance to

like the nebulae above, a fusion of stardust and the unknown

like a miasma of sulfur and rot, oozing death and corruption wherever you step

This is the go-to for development in my book, because if your character has a personality trait, congrats! You’re half way there!

—Confidence:

Can lead to selfishness, over abundance of pride, stubbornness and unwilling to admit wrong doings/beliefs/actions.

—Extroversion

Unable to understand proper boundaries that others have set, tries to bring people out of their comfort zone even when unnecessary, rude.

—Intelligence

One of those nerds that every class has that reminds the teacher of the homework, looks down on those less intelligent and doesn’t care of the social/economical/personal reasons as to why they don’t share the same intellect, prideful.

—Kindness

Nativity, allows the wrong people to walk free, toxic positivity, doesn’t want to understand how some people may just be evil, leading the team into multiple dangerous, avoidable situations.

—Romantic

Quirk—a peculiar trait; idiosyncrasy; memorable little things about a character’s personality that make them charming, endearing, weird, or unique; can be cute habits; is anything worth describing about a character.
