Interesting. How does genetic memories differ from other memories/skills?
They are obviously shared between all members of an organisation, but so are other Background and Career skills. Perhaps the background Bene Gesserit could include 50 hard wired skill points from genetic memories?
If it’s knowledge about the organisation and its secrets, I think a simple Lore/Knowledge skill works fine, like Lore (Bene Gesserit).
But someone like Paul Atreides’ sister is more complex. She works more like a futuristic cyber-shell, downloading all knowledge as a fetus from her mother, being born with the mind and powers of an adult.
