There are frequent references in Ada to "Bras d´Or" which have certainly nothing to do with "Brasil" and, geographically doesn´t even come close to it.
I wonder if this "d´O" is to add more emphasis to the other "d´O" characters ( Baron D´O or Skonky ) or if it is a reference to a famous vintage cognac, Hennessy´s " Bras d´Or".
