A/N Holy crap! So many reviews! I love you all.

Answers to the questions:

Lucas isn't Voldermort's blood child. He's muggle born, and Bellatrix found him in the ruins of his house after an attack. When she brought him to Voldermort, he realized that for a baby to survive the attack, he would need great power. So, Voldermort made Lucas his heir and made Snape and Narcissa raise him.

Neville didn't get together with Luna. He's with an OC. While the Neville/Luna pairing is pretty cute, I think Luna's too out of it to be compatible with Neville. She'd scare him.

To clear things up:

Matt Weasley is Bill and Fleur's son, a 2nd year, age 12. Cousin to Rose and Harry.

Rose Potter is Harry and Ginny's daughter, illegitimate because Harry was killed before he could marry Ginny. She's a 1rst year, age 11. Best friends are Harry Weasley and Lianne Lupin, whom she grew up with.

Harry Weasley is Hermione and Ron's son. Named after Harry Potter, of course. He's 11 and a 1rst year. Best friends are Rose Potter and Lianne Lupin, whom he grew up with.

Lianne is Lupin Tonks' and Remus' daughter. She's 11 and a 1rst year. Best friends are Harry Weasley and Rose Potter, whom she grew up with.

Lucas 'Nielson' really doesn't have a last name (Riddle, I guess). He's 11 and a 1rst year. More about him above.

Lotte and Calder Longbottom are Neville's twins. Both 11 and 1rst years. Friends with Lianne/Harry/Rose.

I'm not going to tell you what I mean by 'save the dark lord's heir,' but know that Rose and Lucas aren't gonna kill each other.

I'm going to end Rose's first year at Hogwarts here. Then I'm going to skip ahead to 7th year, because that's when everything exciting starts happening. When I finish that, maybe I'll go back and write her 2nd though 6th years.

If you have any other questions, leave a comment and I'll answer 'em. Hope this helped, sorry it's so long.

'Abeo toothpick!' Rose muttered. The toothpick twitched a little, and then broke out in bright purple polka dots. Rose swore under her breath, and looked around vainly, hoping for some sort of clue.

Harry wasn't having any luck either. In fact, his toothpick hadn't done anything exciting other than fly up and begin whacking him on the nose. He hit at it with his wand, and it fell back onto the desk.

Rose started to giggle. Lianne looked suspiciously at her toothpick, and cupped a protective hand around her nose.

'Ms. Lupin, kindly focus your attention on your toothpick instead of your nose!' Professor McGonagall glared sternly. Then, taking in her rather exasperated class, she sighed.

'Now, it's swish and jab, none of that delicate flicking nonsense from charms…'

'Abeo toothpick!' Rose said, swishing and jabbing accordingly. Her toothpick gave an indignant shudder, and changed into a small brown bobby pin.

'Twenty points to Gryffindor! Very well done Ms. Potter, very well done!'

Lucas sneered.

Before anyone knew it, the early days of fall morphed into a chilly Halloween night.

The Great Hall was lit with orange and black candles, which cast sinister shadows upon the great stone walls. A red, blood-like punch was served in black goblets, along with several other types of 'interesting' food.

'Hey, this pumpkin thing's pretty good,' said Calder through a mouthful of orange mush. Lianne jabbed at it suspiciously with her wand.

'Yeah, sure, if you like baby food.'

Calder glared at her, but pushed his plate away.

'Gee, thanks Li!'

'Ha,' said Rose 'it rhythms!'

Harry rolled his eyes in perfect imitation of his mother.

The ghosts were serenading the students when Rose decided she had had enough.

Feigning sickness, she stole quietly to her dorm, and took out the invisibility cloak from under her bed. She knew she should've brought her friends, but she wanted to have a go at it herself.

After all, it had been her father's and her grandfather's.

Down in the dungeons by the potions room, Lucas was huddled in a corner, talking earnestly to a mirror.

'But sir –'

'Lucas! You are the Dark Lord's heir! The Dark Lord himself chose you to follow in his stead, and the least you can do is honor him by not letting some little bitch lose you respect! Especially,' Snape hissed from the mirror 'a Potter bitch.'

Lucas sighed. When all was said and done, he really loved learning magic (as much as Rose, unbeknownst to him), and the last thing he wanted was to do something that could get him expelled.

'Yes, sir. What is it you suggest I do?'

In the mirror, Snape's list twisted into a cruel smile.

'Find out what she fears, Lucas.'

'But sir, she fears nothing! Nothing!'

Snape rolled his eyes.

'For the Dark Lord's heir, you are dim-witted. Those that are brave and good always fear harm will come to the ones they love. It is their weakness. Use it to your gain, my Lord.'

Snape's face vanished from the mirror. Lucas put the mirror face-down next to him and sighed, burying his face in his hands. Unaware that Rose was watching him interestedly from under her invisibility cloak, he began to talk to himself.

'But what if I'm not sure I even want to be the Dark Lord's heir?'

Later that week, Rose crept out to her Father's tomb, as she had a habit of doing when she was upset.

'So, Daddy, he's Voldermort's heir but he doesn't want to be? He just seems like a prat to me, that's all. And what if that's because he's afraid to be friendly? Well, Daddy, I can tell you that if he's a prat to me, then I'll be a prat to him.'

Surprised to hear chuckling behind her, Rose looked up.

Aberforth Dumbledore stood beside his brother's tomb, blue eyes twinkling. Today he wore a black and white checkered robe and sported a hat with chess pieces glued to it. In his hands was a bouquet of baguettes.

Plucking one from his hands, he laid it at the foot of her Father's tomb, smiling as he noted the rose at the foot of his brother's.

'Spoke like a true Gryffindor, Ms. Potter.' Then his eyes grew serious. 'But what's this about Voldermort's heir?'

Rose told him everything. He nodded grimly, and then began muttering to himself. Rose stared at him, unsure of what to do. Finally, just as she was beginning to edge away, he looked up.

'Ms. Potter, should you ever happen to stumble along any such information again, please come to my office at once. The password at the moment is 'twee' but it changes regularly. Go to Minerva McGonagall if you cannot gain admittance. She will help you.'

Rose nodded.

'Thank you, Ms. Potter. Now put on that cloak of yours and run up to the castle. I, of course, haven't seen you here and you won't be late for dinner.' Smiling at her, he turned to his brother's grave.

Slipping on the cloak, Rose hurried back to the castle, lost in thought.

Abeo means 'change' in Latin
