Better communications between worlds and no wars. No attempts to invade someone else’s planet, which is something guaranteed to generate annoyance. No dumping of litter in space (humans, take note). For wild places to be left for those creatures that need them and as a reminder nobody can conquer everything. Nor should they.
A better form of border control than the dimension barriers as despite all the magic put on them (and the security people at the barriers themselves), someone always finds a way through the lot. This someone is usually Eileen. The Queen has been known to take advantage of suspected weaknesses but, of course, considers it’s perfectly all right for her to do this. Some of the dimension barriers the Queen would like permanently sealed - once certain people have left dodgy worlds and returned to where they belonged of course.
The unity that binds the realm together when it is faced with the threat of alien invasion to continue once that threat has been eliminated. The Queen and her Council see no reason why it shouldn’t continue given they have no problem with the existence of witches and wizards as long as they don’t plot against the fairy government.
Magical Beings and Treatment Thereof...
Magical beings not to be ill treated by anyone and for such beings not to ill treat each other. An end to the snobbery that gets in the way of lower magical ranks assisting the Queen (after all she needs all kinds of services to help her run the Kingdom well). For fairy stories to be treasured properly… For illustrators to be well rewarded for their wonderful works.
