Looking for a certain fic (FOUND)

[bakafia-kawaii.livejournal.com]

So I can only remember some vague details:

1. Draco rounds up all the pureblood children and escape to Beauxbatons directly after the war

2. Because all the pureblood are leaving (and taking away their magic with them), magical community is slowly disappearing as well

3. The only way to save magic is to court the pureblood children back

4. In the end Hogwarts is unsaveable I think

Thanks in advance :D
