Sigh ... ok, ok. Copyright exists on the works of authors up to 50 years after the death. Use of certain words and phrases within Avalon MAY infringe these laws. Rather than find out the hard way, it is better to change those names and phrases.
Certain DIFFERENT names within Avalon come from ancient mythology and, some say, invoke the wrong atmospheric feeling. While these names are OBVIOUSLY copyright to no one, if they are to be changed why not make the changes all at the same time once and for all?
It is quite amazing how a little bit of line noise can mess up the meaning of your message! I hope this makes it more clear. While we are on the subject, can anyone lend me three and fourpence? I hear there is a dance on! <Gibber>
