Untold stories: who am i?

I saw,
The world in a different way.

I speak,
What the others can't say.

I found,
A way to gain eternal life.

But the price,
I paid is sharper than a knife.

My destiny,
Is foretold by the sear of old,

I Am Me,
Not what the stories told.

I Am a Watcher,
The one who defy fate.

I Am a Survivor,
No one can dictate.

I Am a Bearer,
who walks on the path of exhort,

I Am a witness,
Of L'ife and D'eath
