>>5480070>Servoskulls use still living brainsDepends on the Servo Skull. Many of them are described flat out just dead skulls from thousands of years ago used to house cogitators, not all of them are semi-living cyborgs. I'd dare to wager the majority of them are just flat out skulls housing computers and only a minority of them have brain matter. One of the BL books mentions the Mechanicum fetish for 'housing common technology in the bones of the dead' which was a complaint from a scientists from Corvus Corax previously indepedent tech world.
It's all supposed to emulate ossuary relics.
In any case, Servo-Skulls are exactly what I was referencing when I mentioned "bones of the dead".
Lucian Techpriests may not necessarily die of old age, but I'm pretty sure some of them do still die from the occasional battle. All the more reason those whose brains can't be recovered wouldn't just have their bones be ground to dust, they'd be servo-skulled no?
>>5480056Not the bones of ALL dead, just the bones of the honored dead. Saints and martyrs, priests and such. I have a hard time seeing us using the skulls of worthy techpriests and just grinding them up to corpstarch.
