I've been playing around with writing an adventure for HârnWorld, Columbia Games' real fantasy world designed for any roleplaying game system. The adventure is inspired by Daggerfall, of all games.
I can't say much, but this is actually my first adventure in a long time. Hopefully something good will come of it. As for Hârn World, I can say some things about it from the FAQ.
Hârn is an island on an imaginary world called Kethira. This island and world are the setting for a fantasy role-playing game. The proper spelling of Hârn has a carat (^) over the 'a'; in LaTeX it would be spelled H\^arn. Sometimes the word Hârn is used by players to refer to the entire world of Kethira, or at least those parts that have been described in official and fan-developed publications.
