Allow me to provide a more detailed explanation.
Okay, I think some people will say that Black Lance is not the name of the organization in question, but the name of their super-advanced fighter (Dragon being the name of one arm of the organization's forces or something like that). While this is true in the novel, the game calls the organization the Black Lance, so take your pick on what you want to call it.
Anyway, the Black Lance (or whatever you want to call them) is a group of genetically engineered men led by the superman named Seether, and was founded by Adm. Sir Geoffrey Tolwyn in the hopes of preparing a flawless fighting force to protect the Confederation when a race more deadly than the Kilrathi invaded (Old Geoff didn't live to see the Nephilim, however). In order to provide a proper training area for the Lance forces, Tolwyn created a war between the Confederation and the Border Worlds, fueled by BL forces. Tolwyn also eliminated certain groups of people he felt were inferior, separating the wheat from the chaff so to speak.
So, that's basically what the Black Lance is. Also, there's something about a guy named Whittaker and the Belisarius Group, but screw that. I don't feel like trying to figure out what the hell was going on with that.
