Okay. I will explain. :-) The spire was the most prominent building on the island. It was this huge black tower. It was also magical. It was inhabited by a sorcerer. We never new what his name was so we just called him 'the Man' - very creative I know. He used its power and his own to torment us. He brought in evil beings or created situations to make us suffer. The people on the island lived like that for a few years. In 2017 Lucy's Mom, Katherine, rallied people to fight back. Many joined her. My adoptive parents, for example. This is where my timeline differs from the one you are in. In my timeline, everything went wrong. We lost and He started to get even more cruel. There was nothing we could do. My parents, all of them, we tried. My Mom is strong, Lucy's family, they are strong. The Jedi. The wizards. The Avengers. No one had a chance. He was angry and he hunted us down. Not all at once but one after the other. I think it was a game for him. Eventually, we just tried to survive. Don't draw his attention. Hide. That's why I am not as good as Neville at magic. The people who were able to train me died. Rachel's Mom. Lucy's family. We all grew up changing parents and guardians here and there.
When some of us were pulled back into this timeline, it was before the attack. We told them not to do it. They did not stop. I think it made them angrier. But they changed their plan. This time around it worked. That's why we are all here.
