Being a Tech Priest in the Dark Heresy/Rogue Trader universe, my (personal) first and foremost need is to accrue Servo Skulls. I have already acquired one, and I am already lining up plans for another.
However... this second candidate for my posse is a Kroot.
Can I / should I use a Kroot skull for my next Servo Skull? Is that allowed in the lore?
