Oneshot. No money made. Fenrir greyback
Fenrir Greyback wasn't always a werewolf. He wasn't always a stone cold killer. He'd been married once, had a family also. One horrible night ended it all. For quite a few months, a wizard calling himself Lord Voldemort had been gathering support among the pureblooded families. He wanted to close the wizarding world off from muggleborns and halfbloods.
He started wooing Greyback, unaware that Greyback was married to a muggleborn witch. He had three girls and two boys. The girls' names were Margret, Alyssa and Jasmine. The boys' names were Ian and Malcolm. Their mother's name was Ramona and Fenrir loved her dearly. She and their children were his pride and joy.
Greyback was an Auror. He patrolled a hundred mile radius around his home town. One night, after watching his children in a school play, they were all walking home. The girls, sixteen, fourteen and eleven, were looking forward to Hogwarts and were excitedly talking about it. The boys, ten and nine, were talking about Quidditch, as usual.
Suddenly they were surrounded by werewolves. Greyback sent a Patronus asking for back up as he pushed his family behind him and began fighting them. He had managed to fight off about half the pack when Death Eaters showed up. They told him they would help him if he would just turn from the Aurors and join Lord Voldemort. He refused. Now he was facing not only werewolves but also Death Eaters.
As one of the Death Eaters placed him under the Crucio, the rest began shooting cutting spells at him. He knew he was growing weaker, he pulled off his signet ring and threw it to his wife. He told Ramona to get the children to her. The ring was a portkey. It would take her and the children home. He told her to lock the doors and windows and stay quiet until he got there. He looked back in time to see his family vanish.
Now, he could fight the wolves and Death Eaters without holding back. Spells, hexes and curses were all flung so fast there was no way to tell who had thrown what curse. He felt an awful pain in his back, like he'd been stabbed with five different knives. He knew what had happened. One of the wolves had just sunk a claw into him. It was the night before the full moon. The wolf wasn't transformed but it didn't matter. It was still close enough that he would be infected.
He screamed out in anger and started blasting the reducto curse at every wolf he saw. As the wolves saw their comrades torn apart, they began retreating. They had done their job. They had kept him distracted and turned him. The Death Eaters had long abandoned the scene and, as he found himself alone, he suddenly wondered why. The only reason he could think of was his family.
He Disapparated and reappeared at his home. He ran into his yard but didn't make it very far. He fell to his knees in despair. His family, his beautiful, precious family hadn't made it into the house before they were caught. They were dead. He let out a long wail of grief as he stared at the Dark Mark hanging in the sky over his house.
He heard numerous whooshes behind him. The other Aurors had finally arrived. Alastair Moody appeared beside him. He clapped a hand on Greyback's shoulder but didn't say anything. There was nothing to say. They had arrived too late.
The next day, Greyback handed in his Aurors robes and badge. As he left the Ministry of Magic, he was joined by the werewolf pack who had attacked him. "We need members and you are strong. You are now counted amongst our pack. You need not worry about standing alone anymore. You have us now."
The day after that, Lord Voldemort gave him the same offer. He took it.
