Fall of the Kingdom?

The Ravenmaster of the Tower of London (there really is such a position!), has reported that one of his ravens has gone missing, presumed dead (https://www.theguardian.com/uk-news/2021/jan/14/tower-of-london-raven-missing-feared-dead). Legend (we really need these in these present times) has it, that the 'kingdom' will fall, if fewer than 6 ravens hang around the tower. I suspect that the ravenmaster is already bringing in a replacement. Of course, it could be the case, that Merlina (the missing bird), has simply flown the gig. Lockdown means no tourists, with the added snacks and entertainment, they normally bring to the location.
