Our Fate ・S. Black・(Harry Potter Era)

On October 31 1981, it was believed that mass murderer Sirius Black had betrayed James and Lily Potter and surrendered them to Lord Voldemort in order to help kill the baby boy with emerald eyes due to a prophecy stating that he would be Voldemort's downfall.

But, in this story Sirius Black was not alone, oh no.
The Ministry believed that Black was aided in his crimes by no other then his lover Silvia Snape, yes you heard that right, Silvia SNAPE.
Oh yes, Severus Snape had a sister, a twin. She was his best friend, older than her by 30 minutes.

It's believed that Silvia has also murdered muggles and was also a loyal follower of The Dark Lord.
After all, she was a Slytherin, all Slytherins end up as no good deatheaters...right?

Severus Snape hasn't seen his sister since that tragic, evil, mournful night, that is until now..

Sirius and Silvia know that not every story has a happy ending, but will they be able to survive what's to come?
"We're like shooting stars, in the end one of us will fall"

I own no characters in this story except for Silvia Eileen Snape-Black
