Politically correct aside, I'd follow on the Shakesphere theme. How about "Othello"? Or "The Moor"? Or any Shakesphere character for that matter. Even a name like "As you like it" keeps the consistancy in the series (because I hope there's more to come). "Juliet" probably wouldn't work though... Another option is to go with a nation name, like "Madagascar" or "Kenya". Tribal names aren't too bad, but I'd avoid "Pygmi". Even Ghost II has it's charm...
