Creations of Melkor

Ok, I have done all the research that I am capapble of (The Silmarillion is still beyond my level, tho. I only got to the end of Ainulindale before I just couldn't take it anymore) and I still haven't figured out whether or not Melkor created any single beings to serve him. I knows about the trolls and balrogs and all that jazz (which happens to be debatable jazz, but still) but I don't know about any individual servants. Can anybody help me out with this? It's somewhat vital to creating the non-existant plot of my LOTR roleplay (www.xanga.com/the_fourth_age_rp). Much thanks.

May the Grace of the Valar Be with you,
