Those allowed to visit other worlds to bring back samples of other sources of magic they come across (ideally by taking a sample so the host planet doesn’t miss it but if it is necessary to steal then do so, it is for the Kingdom’s greater good). Long term the Kingdom would like to be the source of all good magic.
The Proper Treatment of Books
Books treated with the utmost respect. The Queen and her Council do not approve of the closure of libraries. They see this policy as literary vandalism. The Queen loves all forms of stationery too and enjoys using vellum to produce some exquisite works of calligraphy, the way all books used to be. She would make reading compulsory and thoroughly approves of schemes to make reading fun for the more reluctant reader.
The Proper Appreciation of Pictures
Pictures appreciated for what they are and for their beauty rather than their monetary value. For all to see the importance of art in terms of creativity and therapy. For modern art to recognize it owes its very existence to the art that has gone before (you need something to kick against).
Good Magical Species
All magical species using their powers for nothing but good (and to prove to the evil minded this does not have to be “wet”. After all Eileen is certainly not wet and she uses her powers to accurately defend the Kingdom. Her skills are awesome). The Queen and her Council would welcome almost any reassurance the realm is safe from attack - from internal or external forces.
