The Next Generation: Lorcus and Lysander

Lorc and Sander, Luna and Rolf's twin sons (whoever Rolf is). Personally, I think that Luna should have ended up with Dean or Neville, but I've come to accept this "Rolf" person.
This is the twins in their sixth year. I imagine them to be Fred-and-George-type troublemakers, very mischievous and intelligent. And yes, they are in Ravenclaw...By the way, the sign on their shirts (under the ties) is the deathly hallows symbol. They are true believers, just like Grandpa Xeno.
I messed up on the background again...
