The Two-Board System

How Mimir’s campaign and module boards help you manage preparation.

Origin

The Two-Board System comes from Kanban methodology, adapted for D&D preparation. Instead of one overwhelming to-do list, you have structured workflows at two levels.

The campaign board holds everything that outlives a single adventure: world-building documents, recurring NPCs, player characters, and homebrew content. The module board holds everything specific to one adventure: its documents, NPCs, maps, and monsters.

The split matters because the two kinds of content have different lifespans and different moments of use. Campaign content accumulates slowly and gets referenced for years; module content is prepared intensively for a few sessions and then becomes history. Keeping them on separate boards means each board only shows what is relevant at its level.

For what each board actually contains, see the Campaign Dashboard and Module Prep View references.

Workflow Philosophy

Prepare Once, Use Forever

Campaign content persists across modules. You write the villain’s backstory once, reference it from any module, and update it as the story evolves. Nothing needs to be copied between adventures.

Module-Focused Sessions

When running a session, you enter Play Mode for one specific module. Everything you need for that session is already gathered on its board — no digging through campaign-wide content at the table.

Progressive Preparation

You don’t have to prepare everything up front. A campaign can start with little more than basic info and a first module containing the first session’s content. As you play, you expand what exists and add new modules when the story calls for them. The boards make this incremental approach natural: an empty section is an invitation, not an error.
