I don't own Harry Potter it belongs to none other than the amazing Jk Rowling herself:
Perhaps she was the reason Draco and Snape like Luna Lovegood so much. They had the same name after all but of course knowing those two they would never admit to admiring her. Luna Malfoy was Draco's Aunt and Lucius older sister by two years. She was never talked about or even referred to because she was humble and nice which made her father hate her. Luna was different than most Malfoy's she was kind but she was also very powerful she had a wand but never used it. Her father loved how powerful his daughter was but the fact that they didn't get along because of Luna's tendency to be nice to people made him always find a way to insult her. He loved the fact she didn't ever use a wand but since they didn't get along he always said it was improper to use magic without a wand. However Luna got along with her mother whom she loved so much and was just like her. Lucius at a time was to, when they were younger Luna always tried to please her father while Lucius was dishonored because he wasn't as powerful as his elder sister.
However over time Luna couldn't take being so snobbish and finally stopped trying to impress him, making Lucius the favorite child. Luna loved Lucius's girlfriend and future wife Narcissa, she was so kind and Luna knew it would do Lucius well to have her. Luna was best friends with Narcissa at hogwarts and they were both in Slytherin, she then met another friend named Lily who was in gryffindor. Her only ever male friend which she never told her father about was Severus Snape. She would hang out with Narcissa and Snape and occasionally Lily and they all were great friends. The one person at school which she hated beyond all reason was James Potter although she did find his friends to be very nice. She couldn't stand James because of how he treated Severus and at one put turned him into a tea cup and threw him out the window. Luna never said her last name because her father didn't want anyone knowing a "Thing" like her was his child. Luna always knowing it, but never admitting it to herself was madly in love with Severus, but she knew he loved Lily and was actually greatly disappointed when she married James. In fact she was outraged, but never said it to avoid ruining Lily's wedding.
When Draco was born was the happiest day of Luna's life, she loved him and it was really her and Narcissa who raised him, all Lucius did was make him act like a jerk to everyone. Luna however knew the real Draco A sweet kind boy, she was like a second mother to him and he idolized Luna and she loved him. Luna joined the Dark Lord but did it to protect Snape, when she heard Lily and James had died it crushed her heart, she cared so much about Lily and even though she despised James she didn't want him dead. She knew that Snape would be crushed as well and she hurried to see him and just as she thought he was crushed. Luna then made a grave mistake one she would never in her life regret however and confronted the dark lord.
" You had no right to kill them you monster, I only joined you to protect a dear friend, UNDERSTAND, I could care less about your ridiculous mission of killing your on but you have gone to far, Luna yelled. "Avada Kedavra" Voldemort yelled while pointing his wand at Luna. She stuck out her hand and absorbed it "have you forgotten i'm the most powerful wizard alive, you are nothing but a fool with no power left" stated Luna. "You are out of power now Voldemort, make me a promise, don't harm Draco, Narcissa or even Lucius and don't you dare harm Severus, and i will leave this world i know for a fact you will come back to power but promise me that. "I promise Lady Malfoy" said Voldemort with a weak grin " oh so now you address me properly, you "thing" if you break your promise i will make you suffer….Harry...Its up to you now…" said Luna before taking her wand and pointing it to herself "Avada Kadavra…..For….y..ou…Seve….rus...m...y...Love.." "LUNA!" "No not you Luna, not...you.." said Snape as he ran into the room with tears streaming down his face" "why am i always to save anyone I love" said Snape I...love...you….Severus…..I….alwa..ys…..ha..ve…
pro...te...c..t…...Har...r..y….P..o...tt...er…...an..d…..mos….t….impor...t.a..ntly…
….Dr.a...c..o..." said Luna before finally passing into the light she was strong enough to survive a little while even after being hit by the killing curse.
