Books, series, sagas, worlds, universes

Pendraic gives you five different canvases to write on. Most writers only need one or two. This page is the cheat sheet for picking the right one for what you're writing.

The short version

  • Book. One manuscript. Most writers stop here.
  • Series. Multiple books that share continuity: recurring characters, an arc that spans volumes, a promise that pays off across the whole run.
  • Saga (also: universe). Multiple worlds plus multiple series that share metaphysics, cosmology, or cross-world threads. Think the Cosmere, Middle-earth, or Discworld: many distinct stories, one shared substrate.
  • World. A single setting. One world can hold one book or many; books reference the world for places, cultures, magic systems.
  • Universe. A grouping of worlds (this is the same row as a saga; we use both names because writers do).

When to pick which

One book, no franchise plans

Just create a project on the bookshelf. If you're writing in a real-world setting, you don't even need a world. If your story has a strong setting that drives the plot (Dune, Earthsea, Annihilation), build a world on the side and attach it to the project.

Three books that share characters

Make a series. Books inside the series inherit voice, tone, and continuity guardrails from the series row, so the LLM keeps things consistent across volumes. If they all happen in the same place, build the world once and bind it to the series — every book inside picks it up automatically.

A multi-series universe (the Cosmere, Middle-earth, Discworld)

Make a saga. A saga holds multiple worlds plus multiple series, plus a layer of universal canon — the cosmology and invariant rules every world inside has to honor. Worldhopper characters, shared physics quirks, a divine architecture that threads across the whole library. That cross-world fabric lives on the saga, not on any one world.

Sagas are a Premium feature because the orchestration that stands one up across worlds + series + per-book pipelines is significantly more time + tokens than a single book.

A standalone novel that happens inside a larger universe

A saga can frame a one-book "series" alongside its multi-book series. The standalone novel still inherits the saga's cosmology + universal rules; it just doesn't have other books in its own series row. Useful for novellas and side-stories that share the universe's fabric.

What "saga" and "universe" mean

A saga and a universe are the same thing in Pendraic. Both names point at the same row in your library. You'll see "Sagas" on the bookshelf because a writer thinks of their published catalog as a stack of books and sagas. You'll see "Universes" on the world builder because a worldbuilder thinks in worlds and the universes that hold them. Same data, two doors in.

Asking Penny to build any of these

Penny picks the right canvas from your prompt:

  • "Write me a novel about X" → builds a project with a book inside.
  • "Outline a trilogy where X" → builds a three-book series + outlines for each.
  • "Build me something like the Cosmere / Middle-earth / Discworld where X" → builds a saga (universe) with worlds, a series inside it, and cross-series threads. Penny will ask once whether you want prose drafted for the books too, since that's a different cost profile from structure-only.

The verbs you use steer the intent. Write / draft / pen / compose mean "include the prose." Outline / plan / frame / scaffoldmean "just the structure." When the verb is genuinely ambiguous (build / create), Penny asks once before kicking off the run.

Doing it from the dashboard

The bookshelf has a Books / Series / Sagastoggle at the top so you can see all three side by side. The worldbuilder has a Worlds / Universestoggle. Each tab has its own "New …" button so you can stand a row up without leaving the page or asking Penny.

Edit and archive live on each card. Archived rows are hidden from the active view and don't count against quotas; they can be restored at any time.
