Fantasy is the genre that punishes a forgotten detail. A moon in the wrong phase. A king who outlives his own grandson. A spell that worked differently three chapters ago.

A word processor cannot hold a world. Edda can. It keeps every era, dynasty, law of magic and place name consistent and searchable, so the world on page five hundred is the same world you imagined on page one.

Built for invented worlds

Everything a fantasy world needs to stay real.

Not folders and a spreadsheet. A connected worldbuilding system made for authors who invent calendars, kingdoms and magic.

Custom calendars

Invent eras, months, weeks, moons and holy days, then place every battle, birth and prophecy on a timeline that runs by your rules, not Earth's.

Dynasties & family trees

Map royal lines and clans across generations. See who married into whom, who has a claim to the throne, and which bloodline carries the gift.

Relationship webs

A living diagram of allies, rivals, debts and oaths. When a character betrays another, you can see every thread it pulls.

Magic & lore encyclopedia

A searchable bible for your magic system, gods, languages, factions and history. Set the cost of a spell once, and never contradict it again.

Maps & locations

Keep cities, realms, routes and the notes behind your map together, each linked to the scenes and characters that pass through them.

Series consistency

One project holds the whole saga. A detail you set in book one is still right in book five, because the world lives in one searchable place.

One click from the page

Your whole world, beside your manuscript.

No more flipping between a document, a wiki and a folder of notes. In Edda the world and the writing live together.

  • Link any character, place or lore entry to the exact scene where it appears
  • Search the entire world in a keystroke when you forget a name or a date
  • Character gallery for reference art, plus arcs, flaws and motivations
  • Everything updates everywhere, so the canon never drifts

Plot the epic

Structure that can carry a saga.

Big stories need a backbone. Edda gives you ten story-structure templates and a visual timeline that shows tension across every thread.

  • Ten editable structure templates, from the Hero's Journey and Freytag's Pyramid to Romance and Mystery beat sheets
  • A plot-thread timeline so a war, a romance and a prophecy stay in step
  • Scene-by-scene status, synopsis and notes for a book with a hundred chapters

Questions, answered

Fantasy writing, answered.

What makes Edda good fantasy writing software?

Edda was built for worldbuilders. It keeps your custom calendars, dynasties, relationship webs, locations and a searchable magic and lore encyclopedia in one place, one click from the sentence you are writing, so an epic with many books and characters stays consistent.

Can I build a custom calendar for my fantasy world?

Yes. Invent your own eras, months, weeks, moons and festivals, then place every event in your story on that timeline. It is made for invented calendars, not the real-world one.

Does Edda keep a series consistent across multiple books?

Yes. Characters, locations, lore, family trees and timelines live in your project and stay searchable, so a detail you set in book one is still right in book five.

Does Edda use AI to write my fantasy novel?

No. The Skald is deterministic and rule-based. It checks spelling, style and readability and offers prompts, all computed locally with no language model and no network. It never generates prose. You write every word.

The world is waiting.
Go and build it.

Custom calendars, dynasties, magic and maps, in one app you own forever and never have to connect to a server.
