Prologue

Aug. 1973

Where there is known story, there is always an unknown story lurking beneath fame. This is the story of Jessica Potter, Marauder extraordinaire.

Jessica Potter came from, you guessed it, the Marauder Era, not because she was James' little sister but because of her pure talent. Yes, she was an unknown Marauder. Let's take a look at her story.

"Shut up, Black! I told you a zillion times it's Jess or Jessi, not Jessica!" a brunette haired, hazel eyed girl shrieked.

"Shut it, Potter, I don't care, haven't you realized that yet?!" a boy one year older than her yelled, Hogwarts very own Sirius Black, who was best friends with her older brother, James.

"You should know I'll tell my parents!" she gave up trying to mind her manors and actually shouted back.

"Whatever, Jessica Alyana Potter!" Sirius smirked. Jessie walked away. She hated hey girly name, especially "Alyana".

She would show them she was Marauder worthy and that she did. She saw her chance that same day when Lucius Malfoy mocking the Marauders, her brother James, Sirius, and Remus Lupin. Remus was always the logical one.

"Hey Lucius, MALFOY!" she said the first part and yelled the "MALFOY" right in his ear and backed away.

"Oh, it's only blood traitor Ms. Potter!" Malfoy smirked.

"Hey, Malfoy, meet my fist, it absolutely loves to meet people, like yourself, who are airheads." Jessi said too calmly before allowing her fist to connect with his jaw bone. Jessi was grinning like a mad-person. Luckily they were in Diagon Alley (getting school supplies) so Jessi wouldn't get into trouble. Jessi was going into her second year where as James, Sirius, and Remus was going into their third year, somehow they all pasted to third with fantastic grades.

The guys looked at Jessica in shock. "Jessica…" they said in unison but Jessica cut them off.

"Guys, It's Jessi or Jess, Jessica is way too girly." She said before she put a hex on Malfoy's hair to turn it pink.

James smirked. "That's my Jess, I'm so proud to have her for a sister instead of a really girly sister."

Remus looked thoughtful. "She's got Marauder talent, don't you guys think so?" he added questionably.

"I say she should be a Marauder," James said, "As long as you're careful as to who you punch, okay Jess?" James asked looking at Jessi who nodded quickly.

Let's take a vote. If you want Jessi I raise your hand." All hands went up. "Welcome to the club Jessi!" Remus announced.

"James, when you said "'As long as you're careful as to who you punch'", since I'm a Marauder does that mean I can punch Sirius?" Jessi asked, completely serious. The guys didn't realize she was serious so they burst out laughing at what they thought was a joke.

"I am so going to have to take control." Jessi thought wryly.
