Dancing Queens- Harry potter au

The potters survived , Voldemort was gone.

One night after a fight during the war Sirius slept with a women , what he did not know resulted in his own twins , Adhara and Gemini

Because Adhara looks so much like Sirius she gets starved , her "mother shaves her hair , because it's to similar to " his" as she says , the only two people who knows of her existence is her twin who tries everything she can , but what can a thirteen year old girl do?

One night it went to far that they ran away, no one has heard of them for six months , during an order meeting , the twins knock on their uncle regulus home, but they did not expect "him" to open the door.
