The tower ravens, Dickens, poe

I thought this was a cool article....especially finding that descendants of Dickens ravens live at the tower.
Now, the last paragraph is something I'd not seen before. I'd only ever seen the story that as long as ravens are at the tower, England won't fall....not that the tower wouldnt fall.
