You're right. Not only do the heavens tremble, but the ground itself shakes when people of one heart and one mind devote and sacrifice themselves for a cause that is just. Evil cannot stand against such a group. BTW, did you write Harry's final speech or is that a quote from something I can't quite remember? It's a good one.
Author's Response: Thank you, first of all. Harry's final speech is something of an amalgamation of various sentiments I've heard and read. This assembly of it, however, is all me.
