This poem was not Aurthiel's writing, but the writing of her former lover, Alasornaion. While investigating and clearing his possessions, investigating his treason, this poem had been found, written in Sindarin and hidden away. Not only did the poem convict him guilty, but it explained his reasons for what he had done. Aurthiel always kept the poem with her, even wrote music to it and performed to herself.
Aurthiel played this song for her daughter, then known as her niece, while training her in Eriador.

Unblind:
I am tormented
This soldier's secret purpose
I am filled with regret
For the blood I've spent
But I must do this
I saw with my own eyes
This Curse, our awful price
For all the sins we've done
I lost my own flesh and blood
We'll lose all we love
Do you not see our mistakes?
Can we fix this or are we too late?
We defied the very gods
We are forsaken, unloved
For spilling our own blood, it still runs
Do you not see what you've done
Ever running rivers of blood
Do you not see your goal's in vein?
Unnumbered tears rage, unending pain
Do you not see the reason
I've committed this unforgivable treason?
Do you not see these scars
The Curse rages on
For betraying the Valar
But I will find escape
