Salutations my dear brethren of carnage. I have come here to render the foul forces of the Imperium asunder, To finally put an end to the xeno race known as the Eldar and to enslave the Orks so they can be used as Tyranid bait.
So She sends Her slaves. Very well. You come to your death, vermin. I will clean your vile visage from the fabric of existence, and will snuff out the spark of your life so violently that even She Who Thirsts will shake with fear.
Tell me Urist, has your race actually joined the choir invisible yet? It's been a long time coming and we do frown upon those who keep the Princess of decadence waiting. If you're having trouble doing so may I suggest you pilot your Craftworld into the nearest sun. Slaanesh may even allow your to be quickly consumed instead of the usual drawn-out, but pleasurably consumption instead. I wouldn't bet on it though...
Were you a slave to any other God, I would perhaps amuse myself via warning you of your inevitable doom. But no. You serve - Her - and as such, you deserve nothing. Nothing but the endless void to which I shall cast you, along with all your kind, and there you will scream for salvation that shall never come, for an eternity.
