How it works
Three modes that make your world better after every session, not just before it.
Build your world
Write articles with automatic wikilinks. Every NPC, location, faction, and secret connects as you type. The relationship graph builds itself. Your world knows what references what.
Wikilinks · Relationship map · Depth meter · Timeline · Calendar · Multi-system stat blocks
Run your session
Session mode is built for a tablet propped at the GM screen. Pull up any NPC in two taps. Fuzzy search that works mid-sentence. Reveal content to players in real time via companion link.
Fuzzy search · Pinned grid · Companion link · Encounter tracker · Improvised NPC shell
Update after play
After the session, debrief captures what happened. New NPCs get promoted from improvised shells. Session recaps publish to the player portal. Your world grows from the game, not just from prep.
Session debrief · Player portal · NPC promotion · Session log · World evolution
Who it's for
Solo GM
Run the game you prepped for.
You're running a home campaign for 4-5 players. You need your world organized, your NPCs accessible mid-session, and your secrets hidden until their moment. Skryrún replaces your binder, your Google Doc, and your second monitor of browser tabs.
