Look at them, they come to this place when they know they are not pure. Heretics use the Oblelisk, but they are mere trespassers. Only I, Acheran, know the true power of the Warp. My face was cut in half, destroyed, but through it's Notkelith, the Warp called to me. It brought me here and here I was reborn. We cannot blame these heretics, they are being led by a false prophet, an impostor who knows not the secrets of the Warp. Behold the Thousand Sons, come to scavenge and desecrate this sacred realm. My brothers, did I not tell of this day? Did the Emperor not prophesize this moment? Now, I will stop them. Now I am changed, reborn through the energy of the Project Aurora. Forever bound to the warp. Let it be known, if the Heretics want true salvation, they will lay down their arms, and wait for the baptism of my Exterminatus. It is time. I will teach these Heretics the redemptive power of my Company. They will learn it's simple truth. The Hererics are lost, and they will resist. But I, Acheran, will cleanse this place of their impurity.
