Population Migration / Travel
Back when people were still evolving into the people we are today those who were born too "different" were forced out of their tribes/groups/homes and as more and more kept popping up the large traveling group kept growing and eventually found a place to settle and people decided send the "different" people over that way. The first "different" people were Fairies and Vampires . No one is sure which appered first and it is a contentious topic to modern times. Overtime witches started appering and then shifters- which threw people for a loop with how different they were from the rest and immideatly caused discrimination- though at that point things were already building between fairies and vampires.
