I disagree with the hypothesis. This statement in particular seems to be too great a leap of logic:
Quote:
Malal has a great influence on the Adeptus Mechanicus, possibly as the Machine God himself.
The Chaos Gods and the C'tan are anathema to each other. There is no plausible way that a C'tan could exist in the Immaterium--remember, during the War in Heaven, the main, most effective weapon that the Old Ones/Eldar Gods had against the C'tan was shooting raw warp-stuff at them (see: the Talismans of Vaul). Just as it would be impossible for a Chaos God to manifest in reality, it would be impossible for a C'tan to exist in the warp--and be able to grant daemon-weapons, to boot.
I doubt that the AdMech symbol--the most compelling piece of solid "evidence" that you possess--is anything more than coincidence. Without it, there is virtually no basis for linking the two whatsoever. It is possible, perhaps, that the deity Malal wishes to free the Void Dragon, but the AdMech show no aspects of worship of Malal, apart from their icon, which is hardly conclusive. Why, then, don't the worshippers of Malal have a contingent of Dark Mechanicus clustered to them, and highly advanced weaponry? Why don't the AdMech show any particular signs of hatred of Chaos? They don't nearly match the Ecclesiarchy for zealous anti-warp god fervor.
As I see it, the AdMech are divided between those who believe the Omnissiah to be the Emperor (a viewpoint which qualifies the Admech as a whole for "membership" in the Imperium), as a separate, omniscient being, or the Void Dragon. Malal only that one most tenuous link to them.
And, additionally, how can the background within
Mechanicum reconcile with this theory? The Void Dragon is explored in rather certain terms there, and
Not to piss on your parade or anything, but your arguments have failed to sway me. It is an interesting concept, though.
ALSO, as a fellow fan of Malal myself, I have to nudge you in the direction of the very recent BL anthology
The Heroes of the Space Marines. One of the stories contained within is about the Sons of Malice and the worship of their patron, the rogue daemonic power "Malice", and, rather excitingly, a certain ritual...
