Battle-Spawned Lullabies

Dwell in the battlefield
Pray for my demise
Not a soul
Can bestow
Legend by name
Hero by fate
Forced to combat
Bred as a soldier
Follow my command
Without any questions
Involuntary murder
Sent only to kill
I hath no mercy
I survive waiting for that day
The end has found me
Only to be reborn again and again
