A/N: This story is a gift for my muse Bakashirisuku and her sister, who said hi to me once. It was a special request, and its taken me a while but I hope they and everyone else enjoys it! Please Review!

Lily was sick of watching the Marauders torture friend and not being able to legally do anything about it. It had been going on for the last five years, but it had gone on long enough. This time they pantsed Severus and hung him upside down for all to see. In his moment of embarrassment and rage he had called her a mudblood, but she knew he didn't mean it. He said she was like his sister. She couldn't let anything come between them, and she also had to make it stop before Sev did something monumentally stupid.

So Lily researched a solution over the summer and came up with an idea. She found a ritual to summon Loki, the god chaos and mischief. This made her grin in triumph, and she presented the book to Severus the next day.

"I don't know Lily... I mean I want them to pay, but what if he goes after us instead? He would definitely be unpredictable." Lily nodded.

"I've been thinking about that, and I think I've got a way to make sure he goes after them. From what I read he only does harmless pranks unless you deserve something worse. Potter and co. do everything in the name of Loki, and they are just bullies. I think it would piss him off to hear that." Severus nodded, unfocused as he drifted into thought.

"How are we going to do the ritual without the Ministry coming after us?" That question made Lily grin.

"The Trace is generalized to an area. Because your mum is in the area, the magic of the ritual will be thought to be hers. Even if they thought it was us, because it doesn't require a wand, they have no way of proving it was us without illegally invading our minds. I've done my research Sev." Severus just smiled and shook his head.

"So when are we doing this? And where for that matter?" Lily looked thoughtful.

"Remember the secluded area near the lake? We could do it there, tomorrow night. Gives us the time to gather the things we need to complete it." Severus nodded.

"What do you want me to bring?" Lily just waved him off.

"I already have everything, I anticipated you agreeing so I got it all in Diagon Alley this morning. Just bring yourself." She picked up the book as she stood. "I'll see you tomorrow Sev." Said boy stood up as well.

"See you Lils."

Both teenagers knelt before the herbs they were meant to light on fire to summon the God of Mischief. Lily lit a match and looked at her brother in all but blood, and recieved a nod, making her drop the match. They waited a few minutes in anticipation, then deflated when nothing happened. Severus turned to Lily, dejected.

"Did we do something wrong? I could have sworn we did it right." Lily was about to grab the book to check when they heard a voice behind them, making them jump.

"Oh you did everything just fine. But I can't say I'm pleased to be summoned from home by a couple of mortals. What is it you want? Be quick with your explanations, for my patience is already wearing thing." By this point they had turned to see a tall man with slicked back black hair, bright green eyes, and black, green, and brown armour, wearing a scowl on his face. Lily stood to face him, not one to be deterred. She was too fiery for that.

"We wanted ask for your help. You see, at our school there is this group of boys who call themselves the Marauders who like to think of themselves as pranksters. But they are nothing more than bullies. They pick on almost all the kids, but this year they decided it would be fun to knock my brother Sev here down a flight of moving stairs and they hang him upside down with his pants down during an exams break. Our Headmaster has just brushed it off, and we can't do anything without legal repercussions. And because they say they do it all in your name, and from what I've read you only really punish those who do wrong, I thought of the idea to ask you for help. We aren't going to try to bind you or anything, we just humbly ask for your assistance." Loki stared at the teen girl before him. He liked her. She wouldn't let herself be driven into cowardice by his show of annoyance.

"What's your name, mortal?" Said mortal looked surprised.

"Lily. Lily Evans." Loki nodded his head.

"And you said these miscreants torture your brother in my name." He received a nod from both teens. "Well that simply won't do. I suppose I'll have to help you. I assume you want me to get them at your school.?" He got a grin from Lit as she nodded her head enthusiastically. She then grabbed the hands of the other teen and started to drag him around a sort of happy dance.

"Potters gonna get it, Potters gonna get it!" It was completely childish but neither of them cared. They were going to love this. They both stopped and looked to see the God lounging on the ground, waiting for them. They both sat down near him, and waited for him to speak.

"Now, I do believe we need to plan."
