Worldbuilding

How the canon waterfall data model works — three layers, automatic downstream flow, and why this architecture is built for TTRPG.

Step-by-step walkthrough: build a World Codex, run a campaign, promote content to canon, then start a second campaign and see what it inherits.

Reference guide for campaign overrides, the Canonize action, visibility across the waterfall, and tier limits.

Create and edit the core content blocks of your world: NPCs, locations, factions, items, and more.

Connect entities with wikilinks and explore your world as an interactive knowledge graph.

Define named relationships between entities: allied with, lieutenant of, located in, and custom types.

Track in-world dates and historical events on a visual, scrollable timeline.

Build rollable tables for loot, encounters, rumors, and other improvised content.

Upload and annotate maps, place entity pins, and link locations to your world graph.

Manage a per-world library of NPC portrait images, tagged by species, archetype, and style for fast lookup.

Control what players see using GM Only, Party, and Character-Tagged visibility levels.
