Fantasy is a form of speculative fiction involving magic, adventure, imaginary creatures, and supernatural forces. Setting is essential to the genre, which explores uncanny geographies, constructs languages, governments, and belief systems, and establishes riveting lore. In short, world-building is a pillar of fantasy.
The environment where a magical story unfolds is always directly relevant to the characters, whose interactions with their surroundings define the plot. But a world’s nature can vary: Some fantastical realms are entirely fabricated, while others are grounded in our reality or exist through a magical portal.
Crucially, setting is also how we distinguish the two primary types of fantasy: high fantasy and low fantasy. Their differences lie in whether the story is set on Earth or beyond it.
High fantasy is as thrilling to read as it is difficult to write. The story develops in a fictional, alternative realm (i.e., “secondary world”) independent from our world, which is governed by its own set of rules. These environments are often inspired by elements of Western mythology, including the concept of the "hero's journey,” the conflict of good vs. evil, enchanted items, divine intervention, personification of the natural world, character archetypes, and supernatural creatures (dwarves, elves, fairies, mermaids, dragons, witches, etc.)
The author must iron out every detail to ensure consistency and persuade the reader that the world is real, as imagined as it may be. For example, you might ask yourself:
High fantasy, hence, requires extensive world-building (to support this planning, you might try this questionnaire by The Darling Axe).
Examples of High Fantasy Books
Unlike high fantasy, a story is identified as low or intrusive fantasy when supernatural phenomena intrude on an otherwise normal Earth (i.e., “primary world”). While the former is completely driven by imagination and evokes a unique reality, the latter is defined by the presence of fantastical elements in our familiar world. The environment itself is based on reality and mimics the physical, social, and logistical laws of Earth, but its fantastical dimension comes from the fact that magic is introduced into that setting.
In low fantasy, magic is considered rare, intrusive, or inaccessible to the majority. Sometimes, that magic exists as a world within a world, i.e., the magical realm exists inside of Earth, often in secret. Other times, the storyteller might weave magic into the fabric of the familiar, everyday world.
To write low fantasy, you might consider:
Examples of Low Fantasy Books
Portal fantasy is a type of fantasy in which characters are transported from Earth to a magical realm where the story unfolds. Here, the characters from our familiar Earth are exposed to an unfamiliar realm that possesses its own rules, systems, history, and culture governed by fantastical traits. An example of portal fantasy would be The Chronicles of Narnia by C.S. Lewis.
So, would we call this high fantasy or low fantasy?
Most would agree that portal fantasy would still be a form of low fantasy since the story still assumes Earth’s existence and hence the story unfolding in the magical realm still occurs in relation to our own world. However, one could make the case that low fantasy must occur within the bounds of our planet and its physical and social laws; exploring beyond that would disqualify the subgenre as intrusive.
