External wars are one of the few events which tends to unite the entire Kingdom. Sprites who are usually despised are now considered upstanding members of the community as they fight really well and have a long and fairly good record in coming to the realm’s aid in its hour of need. Naturally once any threats go the sprites resume being, in the general public’s eyes, lazy, ill mannered, fighting brutes, fit for nothing.
The sprite communities have got used to this. It is partially deserved and that which isn’t, well they don’t bother fighting over that. It just wastes time.
The sprite communities have also been set up and accused of causing wars, usually by those witches or wizards, always keen for a scapegoat, who came off second best in the scrap and want the fairy royals to take their temper out on someone else. It has never worked though it has done nothing for the sprites either.
It doesn’t help that sprites do fight amongst themselves, usually for stupid reasons. Sprites are also looked down for irresponsible attitudes to breeding. Where land has been made barren and they breed like rabbits on Earth, there are many who can foresee a war coming simply due to this.
