Nymphadora Lupin
I was Nymphadora Lupin, formerly Nymphadora Tonks, Auror, mother, wife, hopeless klutz. I was killed by my aunt Bellatrix during the battle of Hogwarts. Bellatrix hunted me down through the fighting so that she could kill me. I think she wanted to hurt my mother for going off and disgracing the family by marrying my Muggle-born father and having me, one of the only non pure bloods of the Black family line.
During my time as an Auror, I did many things. I hunted down known Death Eaters, protected innocent witches and wizards, and helped to keep Harry Potter safe. My old mentor, Mad-Eye Moody, used to tell me that Albus Dumbledore had a plan for the boy and that Harry would save the world one day. Mad-Eye believed Dumbledore and I believed Mad-Eye, no matter how far fetched it seemed. In the end, you couldn't ignore the fact that Harry had already survived against Voldermort once when he'd just been a little baby.
During my time as a member of The Order of the Phoenix, I feel in love with Remus Lupin, a werewolf. I wouldn't listen to anything my family or friends said against it. If my mother could follow her heart and marry a Muggle-born wizard while her entire pure-blood family disapproved, I could certainly love a werewolf.
While my mother's family burned her off of the Black family tree, my own family grudgingly supported me when Remus and I decided to get married in the middle of the war. Shortly afterward I found out that I was pregnant. Remus panicked, fearing that our baby would be a werewolf like him, and for awhile, he left. I understood though. Remus had lived a life of hardship and rejection and feared the same thing for his son. He eventually came back, just as I knew he would.
After my aunt hunted me down and murdered me in cold blood, I found myself in a different place. Moments before, I'd been at Hogwarts while spells flew around me, the next second I was in a bright white place with large open spaces and the whistles of trains. Remus was already there, and so was my father.
Now, I sit here and wait, because Remus does. He doesn't really know why he's waiting, but my dad does. He hasn't said it, but I know he's waiting for my mother. I'll wait here with him until Remus knows that it's time to get on the train. When that time comes, I'll convince my dad to come with us. I don't want him to be alone. Mom will find him when it's her turn, but I know my mom is going to be bound and determined to stay alive as long as possible so that she can raise my son and teach him all about the people who loved him so much that they gave their lives so that he could live in a better world.
She'll teach him that a better world isn't a heroic choice, it's the right choice, one everyone should be able to make without question.
