No, there is a faction that you named yourself after, possibly. Cao Cao would have the Xiahou brothers after the yellow turban rebellion and the Nanman had like a couple of scrolls devoted to them.
The warriors of Shu fought with Yuan Shao againest Dong Zhuo (one of the earliest chapters after the red/yellow turban rebellion), so I think Shu was around when Yuan Shao was.
Still I think that the heroes should be powerful enough to take on a lot of men at the same time. Considering that was a HUGE part of the story. It was a story based on history. It wasn't totally a true story. So the thing is, are you using history for your mod setting or the historical novel based on this period in history.
