>>5262804>>5262807I imagine this will be one of the many things we will attempt to pursue as part of the "Great Research/Reorganization Vacation" arc where we're no longer flitting about the Galaxy trying to establish Lucius and ourselves and can sit in our nice comfy Fabricator General chair and spend some years on Sol, talking with Emperor, Uncle Malcador, and maybe even getting to spend some quality time with our wife.
Possibly we can try to make a big list that QM can factor into a timeskip event, so he can just say "congratulations you did all of what could be achieved with the resources on Mars/Terra except these things which are for now beyond even Talos ability, now to head back out into the Galaxy as there's even more science to rediscover and great crusading to be done. At least, that's how I can sort of envision a way to feasibly achieve most of the inevitably gigantic list of things us players would try to do.
In regards to the Thallax specifically, I suppose it depends how versatile they are.
My big dream is for Talos to cook up Primaris-Scale Bionics. Arms, legs, torso, basically the Iron-Father Primaris Body of Malkaan Feirros, and just shoving the brain and any relevant organs into the chest cavity. While it might not benefit from the same geneseeds and enhanced organ survivability of a Primaris, being able to tout bigger and meaner space marines is great. They dont' even have to be wounded, we can just ask for volunteers or even veterans who want to become one with the machine.
a Primaris-Height cyborg would have the same versatility as a space marine where as I don't know if the same is true or not as the Thallax. But if the Thallax is better than a Primaris Cyborg, then that's even more perfect it saves us less trouble and we can just ask Volunteers from the get go.
Why wait for wounding, when it is an ideal to become one with a machine? Just add some mechadendrites and blam, research versaility and fine motor skills. Guilliman moaned that his hands were too big to pick up pieces of paper. Talos would never have a problem like that because he'd just use tiny metal tentacels to pick them up and write on them.
For those Astartes who don't share the Iron Hands/Techmarine mentality of abandoning flesh, Talos could use his Genetor Skills to try and cook up the same genetic formulae that make the Sons of Antaus really large and have even greater healing factor than normal. But if we go through with the Mass Techmarine program, I'm wondering how many astartes will be left who cling to their flesh.
>>5262927Iirc those rules are rather old and not updated for 8e/9e, so the Thallax updated today might even be better. Unless I'm mistaken.
