Ravens of the Tower of London
The Ravens of the Tower of London are a group of at least six captive ravens resident at the Tower of London. Their presence is traditionally believed to protect The Crown and the Tower; a superstition holds that “if the Tower of London ravens are lost or fly away, the Crown will fall and Britain with it.” Some historians, including the Tower’s official historian, believe the “Tower’s raven mythology is likely to be a Victorian flight of fantasy”.

The historian can say whatever he likes. I still say it’s a bad omen.
On the other hand, praying about concerns has never done any harm, so I believe I’ll go that route for the present..
