>>5416344>If we wanted to, we could try mapping the Psyker (and Pariah too!) genes and epigenetics to predict Psi-levels in advance. Considering the Imperium has not cracked it, despite great motivation, I doubt it is so easy.Perhaps not the Imperium, but the Navigator Gene and the Astropath Dynasties are living proof that at one point mankind (probably our creators) had a grasp upon stable genetic implementation of the psyker gene. And we're as close to the Dark Age minds as it gets.
Maybe looking into them or the technology used in their eugenics processes we might see the Dark Age scientist's handiwork.
