welcome to reloadpsi's riddle for BG

REPOST:

Your heroes cannot hear me
They cannot even perceive me
But you can
Further into the heat of the moment
As you fight for your life
I'll still be around a little more
I've had many names
You've read many names
Or maybe just one, it depends on the tongue

the "fight for your life" and "heat of the moment" makes me think it might just be the battle theme?
