So we win? WE DON'T WIN! Well Moons can be blow apart. I mean literally blown apart to the point you could see the other side. Soul Hunter, you glorious bastard. Just most people will not blow apart a moon unless they want to... Like wanting to eradicate some Space Marines because those fuckers are fuckers. What if Vulkan is there... Wait he'd survive... ¬.¬ Vulkan is unknown at this given time. Last seen during the Beast Arise Series. I could go into detail but I'll keep my mouth shut about spoilers and what not in case anyone wants to read it. I will admit that the Beast Arise series seems more a struggle, after dabbling in the Heresy and Primarch Book about Russ I'll probably try to stomach the last three books of the series.
So how are we supposed to stand a chance with three (four?) chaos marines and an Ork? There's a goddamn imperial fleet outside.
Just like Daddy Konrad eh? Do the voices in your head tell you you're meeting out "justice?" I'm gonna enjoy meeting them when you and I have a "discussion." And if the Commander gets in my way at the wrong time she and I may need to have a "discussion."
So out of curiosity, how does your plan account for the fact that, upon Commander Mortwich's death, her order is given by the naval boarding party leader, and is swiftly shut down by The Admiral of the fleet, who is the DM's character, and likely going to coincide with his interests with that of the one telling the story?

So the response is to preemptively mutiny against the fleet leader, and start a nice series of space battles among the fleet, possibly leading to hundreds, if not thousands, of Imperial casualties. For four traitors and an ork. Ok, yeah no, let's go with this plan, this is too funny.
