Grimmauld Place, a house with a history as dark as it's name, stood tall in the middle of the night. Invisible to those it considers beneath it's occupants, with eerie walls and rich interiors.
A small giggle broke the silence of the night.
"Shh Reg..climb up here slowly" .
The five year old took his brother's hand and climbed up the roof. The elder black beamed at his younger brother and showed him 'the lights' as he called them.
Sirius ruffled Regulus' hair as they both sat there admiring the city lights and the stars. Feet dangling in the air, the black brothers were happier than in any party their parents hosted.
Soon it became the place where many secrets were shared, midnight snacks enjoyed and tears wiped.
Then came the day they knew was inevitable, the day Sirius's letter came and Regulus found himself sitting alone on that roof.
The day before he took the Hogwarts express, Sirius took his brother to the roof and showed him a star which was shining brightly, "That is Sirius star. It's always going to be with you when I'm away. When ever you are afraid, look up and it'll be there just as I'm going to be there in here", he said pointing to Regulus' chest.
"You'll never leave me?", Regulus looked at his brother with tears in his eyes.
"Never", Sirius said.
"Promise?"
"I Promise"
.
.
After a lot of shuffling and turning, a seventeen year old Gryffindor gave up and got out of his bed. Stretching his arms, Sirius looked at the window. The sky was filled with stars. Draping his mate's invisibility cloak, he started to the astronomy tower.
Turns out that he was not the only one up. He saw a figure sitting on the wall of the tower staring up. Before he could act upon his curiosity, he heard it.
"You promised..".
The voice Sirius would recognise even in his sleep, the voice which laughed with him, the voice he'd never forget.
'Regulus...'
"You promised you won't l-leave me...", Regulus choked.
"You promised..."
Sirius moved a bit closer and saw the tears stream down the younger boy's face.
He couldn't forget that expression on Regulus' face when he left Grimmauld Place, those eyes accusing and pleading him not to go.
He lifted his hand to place it on his brother's shoulder, when Regulus got up and wiped his tears.
For moment their eyes locked and Sirius held his breath. But, the greyish blue eyes shifted past him, staring at the brightest star in the sky.
In a blink of an eye, Sirius was alone in the Astronomy Tower.
Years later, a man with sunken grey eyes and shabby beard sat on the roof of No 12 Grimmauld Place staring at the sky.
"I'm sorry..."
Secrets buried deep in its roots, the air dense with unsaid words, Grimmauld Place stood, in a memory of the brothers who were not so true to their name.
