The Singer is an orc musician that will hunt you down and sing to you in Middle-earth: Shadow of War. I mean, he'll also try to kill you—but he'll do it with a surprisingly durable lute, grappling with your sword as he delivers this rhyming couplet right in your face:

You may have heard of one like me

Wherever the strife, the Singer is there

He slaughters and slays with such merry flair

I sing this song with all my breath

Take heed, for this interlude ends with your death
