Hello? Another dead soul here?

Nothing I've never seen before.
This is your new home.
Relax. You are nothing new here.
I don't feel your pain.
It is neither way a gain.
There is no pain that I'm receiving.

Your long-lost love doesn't make me sad.
I'm chained here to listen on forever.
Your heart is broken. I don't really care.

A long time ago, they chained me up here.
I must listen on to more and more pain.
As time goes by I grow more immune.
I will feel nothing any time soon.
I have become progressively numb.

Okay. So your son is missing?

I've heard that one before.
It makes no difference now.
A mortal. You have passed the gate.
What have you come here for?
Bring back the king and queen who are late?
There is no pain I can receive.

It is your task to try to make me cry.
It is really impossible to do.
Over millions of years, I've grown too immune.
I look in the mirror. I see a truth.

My eternity and my ways have become clear.
Such darkness that mortals would not understand.
I look around my dark and grim land.
With all these truths, I shed one tear.
I have become progressively numb.
