The Order fights a losing battle. There is a traitor among them who is fixated on killing them off. One by one they fall, like chessmen being brushed aside. The lone Slytherin is naturally suspected, even by the ones she thought she could trust. But even as war looms upon their doorsteps, happiness can still be found in the cottage Vivian now calls home...until, of course, someone from her past returns with information that could change the tide of battle, tragedy strikes, and the world that she has built for herself comes crashing down within a matter of days. A new purpose rises from the ashes, and with it comes a new Vivian Blair, who must learn to live without the ones she has come to love. Sirius/OC Season 2 of Vivicendium

Vivian Blair is the summation of everything Sirius hates: a prefect, a pureblood, and a Slytherin. It doesn't matter that she makes a half decent Seeker, has an unnatural obsession for reading muggle books, or even that Lily thinks she's a reasonable human being. Vivian is just a bitchy Slytherin who likes to call him a blood traitor and give him detentions. Fortunately, he has an idea to get back at her for everything she's ever done to him. He should know better than to toy with fate, for the more love poems he writes to Vivian Blair, the less of a prank they become, and the more fate seems intent on getting some revenge of its own.

{𝗕𝗼𝗼𝗸 𝟱} There are some stories that are told, but some others are just meant to be buried away. We have all heard the heroic story of Regulus Black; a Pureblood wizard who joined the Dark Lord at a young age, only to see the darkness within. So he finds one of his Horcruxes and sacrifices himself in hopes of destroying it. Or at least, this is just a small part of a story which we've never been told before; a tale that other than Regulus, only a girl named Alexandra Starling could've known.

{𝗕𝗼𝗼𝗸 3} It is a known fact that Crookshanks was helping Sirius Black to capture Pettigrew in his rat form, back in Harry Potter's third year at Hogwarts. But what if Crookshanks was a human just like Moony, Wormtail, Padfoot, and Prongs? What if she was James Potter's twin sister? And why did Dumbledore do almost everything in his power to keep her identity a secret from Harry? This is the forgotten story of Jenna Potter. *** WARNING: Mature and sensitive content ahead [Marauder's Era] [OC's age: 15-21]

But in hopes of unraveling the truth and proving that Sirius had been innocent all along, she goes undercover as Crookshanks. And so, with the help of Padfoot, they embark upon a new journey together, never intending to let one another go as the promise of a second wizarding war arrives.

{𝗕𝗼𝗼𝗸 𝟮} It all started with a kiss. Or better say, everything ended with a kiss.
