Village Witch
Village Witch - you're correct in the news being his main meaning, the Cavalier (or Rider or Horseman, the name doesn't change the meaning same as the Owls v Birds) was a messenger sent to ride out overland. Travel over land was done by horse, now more typically by cars, hence transport. Unlike the Letter this news delivered by a person - hence why he can be a man, courier etc. He's not a stable boy or a lowly telegraph boy (why we say well dressed in descriptions) and he rides his own vehicle. If he's far away he can foreign too.
These all come from the traditional meaning and emblem. So don't rule them out.
Thank you! I have much to learn and appreciate feedback such as this.
