SPICE: Antumbra

"Some shadows must be kept at a distance, as if inside Antumbra."

The concept is actually the same as in European mythology, just as the dragon protects the treasure, here the sandworm protects the planet Arrakis. More precisely, it protects the most important substance on the planet, the spice. The sandworms' larvae produce a drug called melange (spice), the most essential and valuable commodity in the universe because it makes safe and accurate interstellar travel possible. And if you can't handle the sandworm, you should make smart moves in the dune or stay away from the dune.

Let me introduce you to Paul, son of Leto Atreides, who has many names such as Muad'Dib, Usul, The Preacher, The Mentat Emperor. So Paul is preparing to first ride a sandworm.
