Disclaimer: I don't think J.K Rowling has a fanfiction account, and if she did, I doubt she'd write Harry Potter stories. And you don't want to sue me anyway, I have barely any money.
In the past few months, the mark has been growing. It had faded into a scar in the past years, but in recent months, grown stronger. I remember it the moment it had been carved into her arm, as his very first and most loyal Death Eater. I had sworn a thousand times to remain his most loyal, most faithful, and most devoted. I stay loyal to him here, better here than kissing up to Albus Dumbledore, like Severus Snape. But now, he is coming back. I can sense it, from my mark to my mind. He would be back, to purify the world from the mudbloods and blood-traitors. He would. My master. The Dark Lord.
Her skin burned. The mark was burned black, just as it had when he had summoned them 14 years ago, before his hiding. I let out a laughing, screaming sound, "He has risen! I have waited 14 years for this! 14 long years for him to return to free us, his most loyal servants, so that we may kill all of those MUDBLOODS and the world will be pure once more!"
