It was dark that night. Severus and Lily stayed at home on All Hallows Eve, just like they did every year. They laughed as they watched the twins Titania and Harry fly about the house. The toddlers flew on the toy brooms that James, Lily's one-time boyfriend, gave them for their first birthdays earlier that year. The happiness they shared that night was so complete that it was almost pre-determined that it would be shattered.
Soon after Harry and Titania were put to bed, Severus saw the Death Eaters find their house.
"Lily! Grab the children and run!" He yelled, searching for his wand. Before he could find it, he heard the high-pitched laugh.
"You fool! Did you think you could protect her?"
Severus turned to face Voldemort. "Leave my children alone." He blocked the door, hoping he'd give Lily enough time to get away with their babies.
Voldemort laughed as he killed Severus Snape, destroying the man that had both eluded his people and refused to ally himself with the Dark Lord.
When Voldemort walked up the stairs, he had all of his followers wait outside the house.
He laughed as he killed Lily, who'd begged him to spare her babies. He saw the twins in their cots, sitting up looking at him. They both had their father's black hair, and their mother's green eyes. He decided to kill his future opponent Titania Lily Snape first, then her weakling brother.
He whispered "Avada Kedavera." The green light that shot form his wand seemed to ricochet from one child's forehead to the other before returning to hit him in the chest where his heart resided. The house seemed to implode from the magic within.
The wards fell, and the Death Eaters gasped as they saw the destruction. When their Lord did not exit the house, they panicked, leaving the house abandoned.
When James and Sirius came by later that night, they gasped as they saw the destruction. James screamed his heartbreak as he held Lily's still form.
Sirius shook James's shoulder "Prongs, there's nothing we can do but take the kids to Albus."
"And what good will that do? Lily is dead." James spat bitterly.
"Harry and Titania are alive, and they need to go with their godfather." Sirius reasoned, knowing that James should be the one to raise Lily and Severus's children.
"No." James said, refusing to look at his godchildren. "Albus can protect them, because I won't. I'm going after the bastard son of a squib that betrayed Lily." He stood up abruptly, setting Lily down gently, before apparating away from the house that held the bodies of his former rival and the one woman he'd ever loved.
