Doesn’t exist as such in the Kingdom but each species is expected to be loyal to their own type with loyalty to the Queen overruling everything. There is some regional rivalries in the differing 7 regions where the borders meet but the Queen and Council organize sporting events on the quarter days where any aggressive feelings between regions can be literally played out on the field and nobody thinks any the worse of it. Everybody is expected to do whatever they can to come to the Kingdom’s aid should it be attacked by external forces. So to desert your own kind and the magical world as a whole is bound to be seen as treason by everybody in the Kingdom. Eileen would have been very aware of this. Not that it mattered. She still didn’t care.
Sportsmanship
One of the highest ideals for any species to aspire to, the Kingdom is in awe of genuine sportsmanship where sport is not wrecked by greed, drug taking, any form of cheating and fair play is ensured. The Kingdom admires Earth’s Olympic Games (they know full well some athletes cheat but the majority do not and it is the intention behind the games the magical world particularly likes). The Kingdom was in awe of Bradley Wiggins, not just for his amazing achievements on a bike, but for stopping in the Tour de France so he didn’t get the benefit as his rivals ran into tacks thrown on to the route by vandals. The realm thinks humans need to show that kind of spirit more often (though if it didn’t draw attention to the Kingdom’s existence, the Queen and Eileen would happily curse the tack throwing morons and turn them into something nasty like a hump the Tour de France cyclists have to ride over!).
