what am I

I am death. I waltz through the night as I come to you, you cry, begging me to leave. I am sorry, but I do not take your life, I escort you out of it. I am shrouded in a dark cloak, scythe heavy on my shoulder. I have fallen and now I am forced to reap your souls. But I ask that you do not blame me, I am but a faithful servant to my Lord. I am death.
