A Harry Potter / 9-11 crossover songfic -- Too Much Concept?

Dies iræ, dies illa,
Solvet sæclum in favilla:
Teste David cum Sibyllâ...
(Day of wrath, oh, boy, that day!
That's what David and the Sibyls say! --trans. K. O'Brien)

Everybody in the word processing group got out; but what ever happened to the people who never came back to work? H/D slash.

( Harry Potter and the Day of Wrath )
