Are you ready?' I mentally asked
'I don't know, but we are about to find out.' Shard Emperor responded to me.
So with a kind smile still on my face my arm blurred.
My hand reaching into the prearranged inventory window and pulling out the most advanced weapon I had made to date. A weapon that was composed with pure Noctilth and adamantium, its edge honed to a monomolecular line backed by a core of adamantium, energized in such a way that it can slice straight through any psychic phenomenon, and embedded with the most advanced anti-phasing technology know to Humanity to prevent any and all forms of spatial effects. All of that when wielded by me to be enhanced by my various skills made it one of the most powerful weapons in the galaxy, possibly splitting entire daemon worlds in half if it had sufficient reach.
To those watching it all happened in a instant. Perhaps only the Gods could observe what transpired, but if the audience could they would have seen a matte black survival shovel downsized to that of a regular dagger be pulled out of thin air by the red robed fabricator general with one fluid motion beyond even Transhuman speed and reaction capability.
And there, in front of 300 Companions, two primarchs, and millions of unsuspecting people.
I slit wide open the Emperor's throat.
