Harry and Draco are helping Sirius and Remus clean out and restore Grimmwald Palace for the Order. They find out secrets that map out all that happened in the years after they founded Hogwarts and why exactly Slytherins were hated and how the rivalry of The Lions and The Snakes came to be. That pesky fourth year business never happened. Either way set it the summer before 5th year. RLSB HPDM SSGG

Colorful cursing could be heard through the halls of Grimmwald Palace which was currently being restored and cleaned. Cursing has been going on for a good part of the morning. Something would set Sirius off and the other let him rant. Only now he was running out of the more common cursing and was getting so creative it was border lining ridiculous. Some along the lines of 'your mother was a hamster' and such.

Remus was about ready to throttle him. "Padfoot! If you start having a row with everything you stub your toe on when moving boxes then could you be damned to do it quietly?"

The muffled "Sorry!" was followed by a full five minutes of quiet. Then a loud crash was heard and the cursing started up again. Remus sighed. His back hurt and his hip was acting up again. Neither knew necessary spells to make this easier and to be honest both were rather too old for this.

They needed reinforcements. Strong, hardworking and willing to keep the job silent types. And with just three days until summer break he knew just the ones to call.

Aggravated by the noise, dear old Mrs. Black started to scream again.

….

Draco started to choke on his toast as Harry finished reading his Godfather's letter. "He wants us to do what!" Ron started to laugh. "Oh no, the pureblood prince actually has to lift a finger! Harry, I'm sorry mate but you're going to be doing all the work."

Draco scowled from his place next to harry at the Gryffindor table. "I was just surprised. Instead of spending the summer with my aunt and Harry with his cousins, we get to spend it cleaning out the Black Home." Harry started to grin from ear to ear. "We get to spend it together! And our friends can visit us anytime! And we can explore London and we get to live with Sirius and Remus! This is great!"

Draco didn't have the heart to remind him that it wasn't all fun and games and that they had to work but he thought that compared to his cousin and his family anything was more fun. Still didn't stop Draco from internally moping about the actual work.

….

Harry coughed violently as a cloud of dust erupted in his face. The teen glared at the offending dust cloud as he explored the back room he'd found piled high with everything from priceless ancient relics to cursed heirlooms to scraps of junk.

Pureblood families, he decided, had a serious hording issue. Draco started in after him crinkling his nose and snarling in utter disgust. Only then his eyes widened and he stared in utter fascination at all the knick-knacks and artifacts the room had to offer. Definitely a hording issue, which would explain why Draco kept almost everything he could find that he deemed worthy of keeping.

"Is it just me or do you old families like to keep a whole lot of crap in your houses?" He winced as Draco thumped the back of his head. "We don't keep crap we keep relics."

Harry raised an eyebrow. "So your telling me that old music box you bought for three gallons when it doesn't even work, isn't rubbish?" Draco flushed. "It's-well… it's pretty."

Harry hummed and didn't push his point. Instead he kissed the flustered and stubborn blonde. "Stubborn Slytherin you are." He blushed. "Hush up Harry we need to clean this place out." He quickly kissed him back. "Idiotic Gryffindor"

"Oh do stop gaping Rowena. The lads are in love. "

Harry and Draco spun around to face boxes of junk. They couldn't cast magic, they were underage and Remus had gone shopping. Sirius went with him as a dog. They were alone.

Another voice not giggly as the first but stern echoed in the small room. "Well who do they remind you of? Goodness Helga it simply shouldn't be, but it is!"

"Oh, come now dearie you're scaring the poor pets. You who! Over here darlings, no down to your right, there's a good lad."

Harry and Draco's eyes landed on none other than the portrait of Helga Hufflepuff and Rowena Ravenclaw, young and sipping tea with Hogwarts castle behind them.

Draco raised a fine eyebrow. "Still think this room is full of junk Potter?" He drawled. Harry snorted. 'Smug snake"

"Did I hear you two were from Hogwarts?" The founder of the Hufflepuff house asked. "Yes ma'am" Draco nodded. "My name is Draco Malfoy and this is Harry Potter. It's 1995, the summer before our 5th year. I'm in the Slytherin house and he's in Gryffindor."

"And so polite too! What a charmer." Harry rolled his eyes and Rowena shushed her friend. "Now then boys, I don't mean to be rude but I was wondering if you too were together romantically." Draco blushed and Harry grinned replying. "Yes ma'am." "and are your houses rivals?" Draco nodded. "Of the bitterest kind. We actually used to fight a lot and quite violently."

Rowena sighed. "Ah yes, you do remind me of these two boys I know. They fought constantly, best friends to the end though, however, their story has forever been misunderstood. No one ever knew of the passion between the friends that grew until—well let an old girl live on in her musings."

'Oh no Rowena, you must tell them! It's so romantic, forbidden love. Now then dears, why don't you sit down and listen."

Harry sat down on the floor and leaned against some boxes. Draco sat in between his legs on his lap, trying to avoid the disgusting floor as much as possible.

"This is in fact a story of forbidden love." Rowena began. "Of Godric Gryffindor and Salazar Slytherin. Two best friends that bickered and loved each other for years. Helga and I put a stop to that of course. We got them together but… when we built Hogwarts there was evil at work and when Salazar saved the man he loved, he was also marked as an enemy. There was a misunderstanding that rocked Hogwarts to its very core and caused the house of the snake and the house of the lion to be bitterest enemies for thousands of generations."

"This is that story"

…

Yes it's short, bear with me the next chapter will be up quite soon. What do you think of the idea?
