Rebel Faction limitations

[Ianofsmeg16]

I was just curious whether or not you HAVE to have a slave faction, or can this be turned into a new faction? probably an obvious answer to this and its just me being stupid ~:)
thanks for your help

You probably could rename the Slave faction and set them up as a more coherent faction, but they'd still behave like the rebels. Any provinces that rebelled would belong to them, any random brigands would count as their forces, etc, so I don't think it'd be hugely playable.
