What is Skryrún?
Skryrún (SKRY-roon) is a TTRPG worldbuilding platform and session companion. It is not a static lore database — it is a living workspace designed to follow your game from prep through the table and back again. Everything you create connects, and everything that happens at the table feeds back into your world.
Three core modes
Skryrún organizes your work into three modes that reflect the natural rhythm of running a campaign.
Build
Build is where worldbuilding happens. You write entity articles, draw relationships between people and places, structure your lore into typed entries, and wire everything together with wikilinks. Think of it as your GM binder, except every piece of content is automatically cross-referenced with everything else. The knowledge graph grows as you write.
Run
Run is the at-table view — Session Mode. It surfaces the tools you actually need mid-game: fast entity search, initiative tracking, session notes, and a focused interface for looking things up without wading through your full world. When you enter Session Mode, the search bar receives focus immediately so you can start typing the moment something comes up at the table.
Changes you make in Session Mode — notes, visibility flips, new stubs — persist back into your world. You do not lose anything when you close the session.
Update
Update is the post-session debrief. After a session ends, Skryrún walks you through what happened: which entities were introduced, what was revealed to players, and anything new your players invented or discovered. The debrief turns session notes into permanent world records and syncs visibility changes to the player portal automatically.
Who it is for
Skryrún is built for Game Masters. The full build and run experience — lore authoring, entity management, session tools, the knowledge graph — is the GM's workspace. It works whether you are:
- Running a published adventure with a custom campaign layer on top
- Building a homebrew world from scratch
- Managing multiple campaigns in the same setting with separate player groups
- Running a short arc or one-shot and need a lightweight companion
Players get a portal: a read-only view of the world content the GM has explicitly shared with them. Players can see entities the GM has made visible, follow wikilinks, and browse the party's collective knowledge. Players also have backstory tools to add their own character notes and tie their history into the world's lore. GMs control visibility at every level — players never see what the GM has kept hidden.
How content is structured
Every named thing in your world is an Entity — an NPC, a city, a faction, a historical event, a spell. Each entity has three parts:
Card — the entity's identity. Name, type, tags, and a brief summary. This is what appears in search results, the entity browser, and the knowledge graph nodes.
Article — the rich text body where the actual lore lives. Articles support headings, bold, lists, images, tables, blockquotes, and [[wikilinks]]. Most of your writing happens here.
Block — structured data sections attached to the entity. For an NPC this might include personality traits, an equipment list, a secrets section, or a stat block formatted for your game system. Blocks make information scannable at the table without hunting through prose.
When you type [[Name]] inside an article, Skryrún creates a clickable link and simultaneously adds an edge in the Knowledge Graph — a visual map of how every entity in your world connects to every other. You do not maintain the graph manually; it grows as you write.
You do not have to fill everything in before linking. Type [[Thornhaven]] even if that location doesn't exist yet — Skryrún creates a stub you can fill in later. Build the connections first; the details can follow.
Supported game systems
Skryrún is system-aware but not system-locked. Native support means system-specific stat block formats, entity field presets, and encounter tooling calibrated for each system.
- Daggerheart
- D&D 5e
- Pathfinder 2e
- Call of Cthulhu
- System-Agnostic — for homebrew systems, narrative games, or worlds where mechanical data is not the focus
You select a game system when creating a world. It can be changed later in World Settings.

Mobile app
The Skryrún mobile app is designed for the table, not the desk. It gives you Session Mode on your phone or tablet — look up entities, take notes, flip visibility, and track what is happening in the room without opening a laptop. Worldbuilding and article editing remain in the web app. The mobile app syncs in real time.
