Chapter 1: Goodbye

Inside Hogwarts School of Witchcraft and Wizardry, Severus Snape watched his son finish preparing the runic inscriptions on the floor of the office in which they were barricaded, well aware that this would likely be the last time he ever saw him. As time was now of the essence, Severus pushed his distress aside, and he quickly hurried over to Minerva McGonagall, the current and probably last Head of Hogwarts, who was lying on a tartan covered couch.

"You understand what will happen if this succeeds?"

No longer able to speak, Minerva simply nodded and grasped Severus' hand. She then squeezed it in both a confirmatory and comforting gesture.

After sparing Minerva a smile, Severus turned to his son, who stood at the edge of the runic circle he had just finished drawing.

"Father, you're the best thing that ever happened to me and I…" The boy's voice trailed off as he became too choked up with emotion to continue.

Severus pulled his son into his arms, not ever wanting to let him go. Unfortunately a yell from outside of the door alerted Severus to the fact that his feelings were going to have to be put aside as the time to try the experiment was finally upon them. He therefore placed a kiss on the boy's forehead and let him go.

After being released, Severus' son swiftly stepped into the circle, drew his wand and began the incantation.

As the final word of the ritual was uttered, the wizarding world's most feared adversary, Voldemort, broke through the last ward Severus had placed on the door and entered the room just as Severus' son vanished. Voldemort let out a scream of frustration, but he had little time to do more than that because the magical backlash from the experiment spread out like a tidal wave and, in little more than a few seconds, everything with a two mile radius of Hogwarts was laid to waste.

Severus's final thought was 'we did it' before the darkness took him.

His son's first thought after the transfer was 'oh shit' as he stumbled towards a toddler who was sitting on a mat in front of him. However it was not his tumble towards the child that had caused the rather impolite reflection, but the fact that a bolt of green light was heading directly for them.
