Ravens in the Tower
Ravens have long been associated with the infamous Tower of London. The superstition goes that the ravens who live in the grounds of the Tower are crucial to the continuity of the United Kingdom - if the ravens ever leave, then the kingdom will fall. To ensure the ravens cannot leave, even in our day and age their wings are clipped, just in case. During the Second World War - arguably the UK's most perilous hour - most of the ravens died due to shock caused by German bombardments of London, and only one remained, Grip. After the war ended the government introduced new ravens to the Tower and ensured that they were given rations and had their wings clipped so that the kingdom would be safe.
