Yeah I read that and understood it, it's the past 100 years one that I did not understand. So let me try to see if I have this right. We are the teen vampires or vampyres, which the only difference being their eating habits if I'm right, that were sentence to die by the sun, but some how didn't die or came back to unlife(see what I did there XD) after being left in the sun. After living in exile they are aloud back because the people of the town they were exiled from was more or less wiped out. That it?
