Dark lords need help too

Disembodied Sauron needed something to do his seeing and speaking for him; had the ringwraiths not been so good at sniffing out the Ring of Power, I imagine he could have employed someone to do his smelling for him as well.

I could have easily kept going with this ("Hand of Sauron", "Elbow of Sauron", 'Nipples of Sauron", etc.) but decided to quit before it got out of hand.
