Summary: Luna and Magnus didn't always have a father-daughter relationship. In fact at first, Luna hated him. Set 4 years before City of Bones, Luna Lyn is a 14 year old warlock with zero control of her powers. She wants to learn from the best, but what if the best is an 800 year old party animal who seems to bring in a different person every other week? Introduces my TMI OC Luna Lyn.

Disclaimer: I don't own TMI. If I did, Magnus and Alec would be married by now and would've never broken up… I own the plot, and Luna Lyn.

WARNING: Some very slight Malec. And probably failure writing...

AN: Luna Lyn is a girl that appears in my headcanon as a teenaged warlock that goes to Magnus for help to control her magic and their relationship grows to be that of a father-daughter relationship. This is their story of their meeting and some of the many times Magnus shows his hidden badass side. and plus I think Magnus would make an awesome parent if given the chance.

Prolog: At One Point I Hated Him

"Hey Magnus?" Alec asked. Magnus, a young man with messy black hair, gold cat eyes, and pretty tanned skin looked at a pale boy with shaggy black hair and lovely blue eyes.

"Yes my darling?" Magnus replied. Alec blushed slightly.

"How did you and Luna meet exactly?" he asked. Magnus smiled and pecked his boyfriend on the cheek.

"That is a very interesting and pretty funny story actually. Both of us should tell you that story. Want me to get her?" he asked. Alec nodded, curious about how his boyfriend met the girl he considered to be his daughter. Magnus kissed him sweetly before sliding on a pair of sparkly bright red sweatpants and leaving the room. Alec grabbed his black sweatpants and put them before his beautiful boyfriend returned with a pale and petite but very pretty girl with waist length straight reddish-brown hair and stormy gray cat eyes. She looked sleepy, wearing a baggy t-shirt and sweatpants that were too long for her. She rubbed her eyes in an attempt to wake herself up.

"Damnit…I was about asleep Magnus…what's up?" She mumbled sleepily as she crawled up on the big bed. Magnus smiled and kissed the top of her head. He snapped his fingers and a cup of hot raspberry tea and two cups of coffee appeared on the nightstand. Alec grabbed the coffee and handed the tea to Luna, who sipped on the hot drink happily.

"Alexander wants to hear how we met Luna. And you needed to get up anyway. You were about to fall asleep in your makeup again." Magnus replied. Luna smiled.

"Ahh that story. You know Alec, Magnus and I weren't as close as we are. In fact, at one point I hated him." She explained. Alec's eyebrows raised in surprise.

"Really?" He asked. Both warlocks nodded.

"This story begins four years ago…" Luna began.

I hope everyone likes the prolog for this story... And I feel horrible for posting a story before reading the books (I only have the movie, Wiki, and snippets of the books to go on. Please tell me if I've screwed a character up...
