Pen of Chaos (real name: John Lang) is the creator of a free, French MP3 saga called "Le Donjon de Naheulbeuk" (Naheulbeuk's Dungeon). In addition to the saga, many derived products have been created, including soundtracks. It revolves around a group of stereotyped and typical adventurers in a role-playing fantasy world. Expect Irish folk music with hilarious RPG parody lyrics. Hilarious if you understand French and RPGs, that is.
