The already expansive “Dune” universe is about to get even bigger, “Dune: Prophecy” executive producer Alison Schapker tells CNN.

Prophecy sets itself apart from other Dune media by its focus on female characters, particularly the powerful Bene Gesserit order.

We’ll miss good ol’ Oz Cobb on Sunday nights, but hey—maybe Arrakis will ease the pain of a certain moment from The Penguin’ s season finale. Addison Rae dances in a swimsuit in the back of a truck and wears a sailor outfit for new "Arcamarine" video.

Prophecy rarely visits Arrakis, the spice-rich desert planet's presence is still profoundly felt by its characters.
