What am I

What am I?
Curse or blessing?
Darkness or Light?

Sister I am
My true name forgotten
Isn't it?

You have found me
I found you
Souls reunited

Brother I hear you
Beware of me
Weapon and victim I am

I seemed so strong
But weakness defeated me
Your death I am

I wanted to protect you
My destiny it was
still is

I was strong
So I've chosen the only way
Death

My own it was
But I came back
You didn't recognize me

You didn't hear my warning
You couldn't remember
You saw only the eyes of a stranger
