Erdor, aka Les Chroniques d'Erdor, is a French oneiric fantasy role-playing game written by E. Bouchard and published in 2003 by La Boite à Polpette (BAP), an independent not-for-profit editor from Strasbourg, France. The game was discontinued after BAP's bankruptcy in early 2004, and is now essentially a collector's item.
The storytelling game, set in an imaginary universe populated by unusual species and beings inspired by myths from Antiquity, Africa and the East, featured qualitative game mechanisms using a card game and a d20 System conversion. The first professional printing of the game featured two 250-pages volumes, after initial electronic diffusion.
Les Chroniques d'Erdor was featured as the "best game of December 2003" by the French role-playing association Guide du Roliste Galactique.
A second edition was published in 2008 under the Silence Indigo label.
