Compass Man 🧭

I'm reading about Dune lore and I'm confused about Alia's ancestral memories. I don't understand how Baron Harkonnen can "possess" Alia through ancestral memory in Dune.

Frank Herbert spent 6 books telling us that Ecology beats Messiahs. So why do the movies keep trying to sell us Messiahs?

Who are the soldiers and normal people of Caladan ? Are they also part of the Atreides family and therefore related to paul?

If spice is necessary for space travel, how did people arrive to Arrakis in the first place?

why is Feyd-Rautha Harkonnen the only one that got black teeth.? mf

why in the golly gosh darn hopping fish do we have to suffer so much for dune messiah to come 😭

But why did Chani fall in love with Paul, sleep with him, and build a life with him if she was always going to reject the person he eventually became? Was she in love with Paul Atreides or the version of him she imagined?

Why was House Atreides not allowed to hold both Caladan and Arrakis, when House Harkonnen held both Geidi Prime and Arrakis?

I know spice slows the aging, but it looks like they added a bit of makeup to make Paul look a little older. That or the stress of...everything.

Where the Hell is Thufir after the harkonnen attack?
