The Adventurer's Guide to Eamon

Eamon was made to bring D&D-style adventuring to the computer.
The Adventurer's Guide was made to bring Eamon-style adventuring to D&D.

And what, you may ask, is Eamon? Inspired by Dungeons & Dragons and other imaginative works of fantasy, Eamon is a long-running text adventure game series developed originally for the Apple II computer in 1979. Its setting is the magical world of Eamon, a cross-roads and melting pot where innumerable other fantastical domains intersect and characters of every race and origin freely mingle.

In the decades since the game's release, scores of authors have added their own unique pieces to the world, gradually building a complex and ever-expanding setting that's been enjoyed by countless adventurers over the years... but which until now could only be glimpsed in scattered pieces across hundreds of individual stories.

How to use this guide

Dungeon Masters will find everything they need to run adventures on the world of Eamon:

The menu on the left side of the screen (under the three-bar icon) lists key articles on broad topics: geography, history, races, etc. These are good starting points if you want to see the "big picture" and get a sense of what the world of Eamon is like. Hint: click the gear to reach settings for author's notes and dark mode.

The panel on the right, which you can slide open or closed using the little ribbon in the top-right corner, shows articles on narrow topics: individual people, places, artifacts, and the like. Use these to get detailed descriptions of specific features of the world.

The Adventurer's Guide to Eamon is a free supplement meant to be used with the core books of your preferred fantasy RPG gaming system. For the Dungeon & Dragons series, this means the Player's Handbook, the Dungeon Master's Guide, and the Monster Manual. It focuses only on the things that are different and distinctive about the world of Eamon — it's history, geography, people, and so forth — and generally avoids restating rules, stats, monsters, spells, or other elements that are already thoroughly covered in D&D publications.
