Quote #10
DUMBLEDORE: Relax, dear boy. The stone has been destroyed. My friend Nicholas and I had a little chat and agreed it was best all around.
HARRY: But Flamel, he'll die, won't he?
DUMBLEDORE: He has enough Elixir to set his affairs in order. But yes, he will die.
We never see Flamel, and his activities are only hinted at, but he's important enough that Dumbledore reveals his ultimate fate, and how Flamel's sense of duty is compelling him to surrender immortality itself.
