Grazie! That was quick because someone already made it in the past days!
And by the way I'm at 9
I sacrificed my heart
To ensure the survival of many;
And my sacrifice has been rewarded,
For you destroyed a giant,
(Alas, another sacrifice, you've lost your friend),
But I, we shall not be forgotten.
Who/What are we?
