should fairies and spellcasters share a rivalry?

I would say "no" but I don't necessarily need them to get along (at least not in a happy happy joy joy kind of way). However, I would prefer that their interactions begin neutral (as in no particular like or dislike for each other) because I want to be able to make my own rivalries in any way that I, my own story-maker, see fit. If it were to be done similarly to the Werewolves pack, that would be another automatic pass for me on buying another pack.
