Warhammer 40K: I Have the Emperor's Voice Pack

I used to think transmigrating into the role of an Imperial commissar was unlucky enough, until the Emperor's whispers started reaching my ears. “Three greenskins behind the cover ahead on your left. The one with the bolter is their leader.” “The soldier on your right will be corrupted by Chaos tonight. I recommend executing him in advance.” “Watch out. The navigator on this cruiser is having a nightmare. We may need to make a warp jump.” Now the whole fleet thinks I'm a military genius who can see the future, but I alone know it's just a battlefield voice pack from the Golden Throne. The problem is, the Emperor's instructions have been getting stranger and stranger lately. “Forget the battlefield. Go to the third serving window in the mess hall. They're serving stew today.” “Have the Tech-Priest install a heater in your room. You sneezed last night.” “That Inquisitor is secretly writing nasty things about you. Want me to give him nightmares?” Your Majesty, are you... getting too bored on the Golden Throne?
