Eberron Tiddlywiki at Tiddlyhost
Eberron: A campaign setting for D&D designed for telling fantastical pulp and noir stories.
Tiddlywiki: A non-linear notebook for organizing complex information. It runs as a single html document that you can run in a browser and save and edit locally, even without an internet connection!
I (Will/Ziphion: reddit, lemmy, github) created this tool to be a reference for myself when running and planning tabletop roleplaying games in the Eberron universe using my work-in-progress Storyloom system. It pulls from Eberron material dating all the way back to the original campaign guide from 2004, as well as a wide variety of D&D sourcebooks and other roleplaying supplements. For the full list of references, see References. Because I intend to use this material with my own roleplaying system, most (if not all) direct references to D&D mechanics have been removed and, if necessary, replaced with Storyloom mechanics.
Keep in mind that much of this material has been altered, in small or large ways, in order to match my own preferences or my own vision of an internally consistent Eberron. Some examples:
This document is a mostly complete database of all things Eberron, and I still periodically add to it. However, please note that I have deliberately omitted certain content which I feel to be antithetical to the core concept of the setting as laid out by Keith Baker. Among the excluded content are large swaths of the books Five Nations, Forge of War, Explorer's Handbook, Faiths of Eberron, and other core canon Eberron materials.
Using Tiddlywiki might take some getting used to; reading this short tutorial might help you find your footing. Note that while the site works fine on mobile, it was designed for desktop.
I've also added a two-column plugin, so you can have two "story rivers" side by side. Shift-click a link to open it in the opposite column, or click the "divert" button on the title bar (looks like an arrow curving left or right) to push a page to the opposite column. Hide or show the right column by going to the "open" tab of the sidebar and clicking the "columns" button at the bottom of the section.
As for checking out the tons and tons of Eberron content in this database, I'd start with the Map in the sidebar if you haven't already!
Find Things is a great way to locate specific pages based on category, or even open a random page based on your search terms. If you don't find what you're looking for, you can try the search bar at the top of the page or in the sidebar.
Modern Age is a rundown of major events in the world (particularly within Khorvaire) over the last 3000 years. Pick an event, and then just start link hopping!
