Worldbuilding Open Rules Table Tools

Storycraft for Dice & Delvers.

Build the world, gather the table, publish what you've made. Underneath it all sits an open rules library — every spell, creature, feat and rule cross-linked and source-cited — so what you build stands on real, licensed ground.

Start without picking a system

Build a setting, gather your players at the table, or use table tools before deciding on rules. When you are ready for a system, the library below is waiting.

Worlds

The home for your campaign: your setting, your people and, if you want them, your rules. Usable with any game system, or none.

A reference library built for the table

Every page is cross-linked, source-cited, and laid out for a mid-session lookup. Spells show which class gets them at what level, class options list their real choices, and each open-licensed record carries its licence and a resolvable source chain.

Who it's for

The library is fully open on every plan. Open Game Content attestation — the verifiable Section 15 chain — is free for everyone too. Paid plans give GMs a shared campaign home, authors a named imprint, and studios team seats.

Sources you can follow

Each record shows its chain — content status, contributor attestation, a resolvable Section 15 line.

Every publisher, named

Citations resolve against a directory of real tabletop publishers — the same list a contributor picks from when they attribute a source.

Private until you publish

Nothing you build is public until you run the real publish flow — the one that produces the Section 15 notice.
