What is death?
Sirius dies in the ministry on the 18th June 1996, pushed into the Veil by his cousin while his godson watched, helpless. A laughter frozen in time.
What happens when you die?
He meets his Death, but refuses it. Refuses to give up, give in- refuses to rest.
Is death when you take your last breath on your own, or when people last utter your name?
Sirius awakes nineteen years in the past, now a father, with the will to change the world as he had known it.
Can you refuse Death while staying human?
