The Human League was an evil racist xenophobic new-wave synth-pop organization that operated on Corellia during the early years of the New Republic. Its precepts were based on human superiority to all alien races, which is ridiculous. I mean, if humans really were superior, they'd make up the vast majority of important characters in the entire galaxy...
Well, anyway, the Human League was run by a Grand Wiz—I mean, "Hidden Leader," who turned out to be Thrackan Sal-Solo. He wasn't particularly well Hidden. Thrackan tormented nearby systems with such horrible and catchy tunes as "Don't You Want Me" and "Keep Feeling Fascination."
