"‘Give me your hypothesis, Forgemaster,’ said Helbrecht. ‘I do not believe the cythor are entirely of our realm of existence, my liege,’ said the Forgemaster. [Jurisian] ‘This stinks of warpcraft,’ growled Gulvein. ‘This is not the work of the warp. The geometries of the warp defy explanation of any kind. If anything, these dimensions here exhibit a greater complexity. Many of us have noticed the inconstancy of the rooms here, the lack of match between exterior and interior.’ ‘Aye,’ said Helbrecht. ‘I have seen it for myself’. Jurisian nodded, the movement accompanied by the faint whirr of muscle bundles. ‘Though complex, the dimensions of this place are explicable. This whole habitat is an expression of higher dimensional physics’. ‘Explain,’ said Gulvein. ‘The universe we exhibit comprises four dimensions – height, width, depth and time. These creatures are, perhaps, natives of more’. ‘You speak of the warp,’ said Bayard. ‘I do not,’ said Jurisian. ‘The warp is separate, unto itself, another realm entirely. There are more dimensions than the four in our own field of existence. It is through these that entrance to the warp is affected, and how some of the greater mysteries of the Adeptus Mechanicus are realised, but these dimensions are not of the warp. They are as real and physical as the heft of your sword, or the roundness of your bolts’. ‘I do not understand,’ said Bayard. ‘Imagine, champion, that you lived in a world of three dimensions instead of our four,’ said Jurisian patiently. ‘Width, depth and time. You would have no concept at all of up or down, as there would be no height. It would appear perfectly normal to you. But that would not mean that height did not exist, only that you are incapable of perceiving it. So it is here’. ‘You speak in riddles. If such a place existed, I would be able to see it. I can see no flat world, and so it is not there!’ said Bayard. ‘I speak of the greatest mysteries of the temples of Mars. It is not given to you or even to me to understand them, but that does not mean they do not exist’. Helbrecht spoke. ‘You posit then a creature that exists as a physical being, not a witch or daemon born out of the warp?’. ‘Yes, my lord. These new forms of the cythor are as real as you or I, but possess further dimensionality to them that makes them difficult for us to perceive. Forgive me, my lord, but I am unable to elucidate further. This field of study is the preserve of the greatest of the magi of Mars. My only knowledge of it is practical – the application of these prayer-equations to the proper functioning of field generation and suchlike. I do not know sufficient incantations to reveal the secrets encoded within this man or this building'."
