The Promise

To keep a promise is not a simple thing to do.
Harry promised to Hermione to return to her safe but he gets killed by Voldemort. And Hermione makes promise to revenge upon his death but she risks so much...

AU! It doesn't happen in the books!

Song: Within Temptation - The Promise

The lyrics of the song are important.

On behalf of her love
She no longer sleeps.
Life no longer had meaning.
Nothing to make her stay.
She sold her soul away.

I held you tight to me
But you slipped away.
You promised to return to me
And I believed, I believed.

After the night he died
I wept my tears until they dried.
But the pain stayed the same.
I didn't want him to die all in vain.
I made a promise to revenge his soul in time.
I'll make them bleed at my feet.

Sometimes I wonder
Could I have known their true intentions?
As the pain stayed the same
I'm going to haunt them down all the way.
I made a promise to revenge his soul in time
One by one they were surprised.
