Leo Moser's primary auxlang project is called Acadon.
Some bits have been posted but are outdated. There is no authoritative description of Acadon available as of May 2010.
Moser's project as of June 2010 will be to launch Acadon, and a near twin AbAcadon, as if versions of an artlang in a book in the fantasy genre, a tale of elves set in Oz, and nearby.
Moser has writen a book (with his daughter Carol) called Halloween in Oz. Thus the context has been set for an artlang.
