Understanding Fantasy Subgenres

Fantasy is broad. Know your subgenre:

  • Epic/High Fantasy: Secondary worlds, grand stakes, good vs evil. (Lord of the Rings, Wheel of Time)
  • Grimdark: Morally gray characters, violence, cynicism. (A Song of Ice and Fire, First Law)
  • Urban Fantasy: Magic in modern cities. (Dresden Files, Rivers of London)
  • Portal Fantasy: Characters transported to magical worlds. (Narnia, Alice in Wonderland)
  • Low Fantasy: Our world with subtle magic. (Game of Thrones early books)
  • Sword & Sorcery: Action-focused, personal stakes. (Conan, Elric)

World-Building Fundamentals

Your world is a character. Build it thoughtfully:

Geography & Environment

  • Climate, terrain, natural resources
  • How geography shapes cultures and conflicts
  • Flora, fauna, and magical creatures
  • Important locations and their significance

History & Lore

  • Major historical events and their consequences
  • Origin myths and legends
  • Ancient civilizations and their remnants
  • Ongoing conflicts with historical roots

Society & Culture

  • Social hierarchies and power structures
  • Religions, beliefs, and superstitions
  • Customs, traditions, and daily life
  • Languages and naming conventions

World-Building Trap: The Info-Dump

You'll research and create ten times more than you'll use. That's fine. The iceberg principle: readers see 10%, but you know 100%. Only include world-building details that:

  • Are relevant to the current scene
  • Reveal character or conflict
  • Create atmosphere or stakes

Creating Magic Systems

Brandon Sanderson's Laws of Magic provide a useful framework:

Hard vs. Soft Magic

  • Hard magic: Clear rules, costs, and limitations. Readers understand what's possible. Magic can solve problems (because we know its limits).
  • Soft magic: Mysterious, undefined. Creates wonder but shouldn't solve problems (deus ex machina feels cheap).

Key Questions for Your Magic System

  • What can magic do? What can't it do?
  • What does magic cost? (Energy, materials, time, sanity?)
  • Who can use magic? How do they learn?
  • How has magic shaped society, warfare, and daily life?
  • What are the consequences of misuse?

Fantasy Character Archetypes

Fantasy has beloved archetypes. Use them as starting points, then subvert or deepen:

  • The Chosen One: Destined hero. Make them earn it or question the prophecy.
  • The Mentor: Wise guide. Give them flaws, secrets, or their own arc.
  • The Dark Lord: Ultimate evil. Give them understandable motivations.
  • The Rogue: Morally flexible ally. Test their loyalties.
  • The Warrior: Skilled fighter. Give them emotional depth.

Plotting Fantasy Stories

Fantasy often uses classic structures:

  • The Quest: Journey to find/destroy something. Physical travel mirrors internal growth.
  • Coming of Age: Young protagonist discovers powers/destiny. Popular in YA fantasy.
  • Political Intrigue: Power struggles, betrayals, shifting alliances. Requires careful tracking.
  • War Epic: Large-scale conflict. Multiple POVs show different perspectives.

Avoiding Fantasy Clichés

Fantasy is rich with tropes. Some to handle carefully:

  • Medieval Europe as the only setting
  • Elves/dwarves/orcs copy-pasted from Tolkien
  • Prophecies that remove protagonist agency
  • Female characters as prizes or props
  • Magic with no cost or consequences
  • Evil races that are uniformly evil

You can use these elements—just add your own twist or examine them critically.

Writing Fantasy Prose

  • Balance description: Enough to immerse, not so much it bogs down.
  • Ground the fantastical: Readers need relatable emotions and sensory details.
  • Consistent naming: Decide on linguistic patterns for places and people.
  • Avoid modern language: "Okay" feels wrong in medieval settings. Be consistent.

Fantasy Word Count Guidelines

Fantasy readers expect longer books:

  • YA Fantasy: 60,000-90,000 words
  • Adult Fantasy (debut): 90,000-120,000 words
  • Epic Fantasy: 100,000-150,000+ words
  • Urban Fantasy: 80,000-100,000 words
