Quoted By:
"I do wish to meet my creator and examine law if he holds some form of rights for my anatomy within Martian regulation"
I love that's what Talos first thinks of the Emperor, creator not father, and the rights of anatomical propriety
I'd like to hear your guys take on it but for me it fits for many reasons. Techpriests recognize first the creator and created, not father and son. What a techpriest clones or makes in his lab does not automatically become their son. It is a relationship that has to be earned, like the techpriest who chose to make a female clone his daughter defying the norm of the cloned apprentice
For me Talos already has a father, C4R. Not simply "adopted" father, but a father. One who chose to raise Talos and train him as son. What does adoption even mean to a techpriest anyway, who usually don't sire things in the traditional sense anyway? Does it matter whether or not he holds any genetic relation? Of course not! Ascribing works to ties of the flesh is, well, a weakness of the flesh. Not that we'll disrespect the nobles for believing it but. . . its just not necessarily the techpriest way. Vera and Trig are also our children, and let no one tell us otherwise.
I think C4R is our true father for raising us as son, just like we are the father of our Acillians for raising them by our efforts, not merely because of our genes. In that regard we are their creator and gene-sire, but we choose to make them our sons. True C4R may not be our biological gene-sire, but he will always be our father. It took Roboute 10,000 years to recognize that about Konor, and only after having met the Emperor's logical true form
The other big reason is I think approaching the Emperor as recognizing we are one of his created tools to fulfill a purpose fits his plans better. Lore wise its heavily implied he really, truly wanted 20 tools to fulfill his task first and foremost. He only let the Primarchs call him his sons but that wasn't the original intended purpose, and he rarely called them his sons himself. I still think he liked them though, as any techpriest likes a favored creation or progeny (Cawl and Felix), beings closer to his level, but they were tools for mankind foremost. As all beings of man should be, tools to serve the greater humanity
The only drawback is our religious faith, but unlike Lorgar we actually make use of it not hinder us, and we don't shove it down other's throats. Service is our prayer, factories our temples, and progress of the great crusade our worship. Not useless temples and effigy's. And if you don't believe in the Machine God, as long as you don't blaspheme his machines, we don't care
When Guilliman met the Emperor he felt "not as a favored son returning, but like a Craftsman who found a favorite tool he had believed lost" and was crushed by it. To Talos, as all techpriests who want to become tools for the Great Work of the Machine God, that would make him happy, not sad
