Not a silly question at all. I'm leader of the 13th Legion, a well-known Imperial PvP group. We are dedicated to the Empire, and we show our dedication by defending Imperial space (and CG's) and attacking Federation targets and CG. Eravate is now running a CG that supports the Federation, so we are opposing it. Before the fight started, I sent them a message that said: "This CG is under 13th Legion Imperial blockade. Any ships aiding the Federation will be destroyed. High-wake or die!"
Of course, coming from an Asp when you're in an FDL and Python, you would probably ignore such a warning as they did. I had my primary pvp ship (and FDL) in system, but I like flying the Asp because I get more people who try to kill me.
