Idaho was introduced in Frank Herbert’s originalDunenovel as the loyal Swordmaster to House Atreides.

It almost appears like he could be the charismatic hero of the prequel show.

However, there’s much more to Desmond Hart than what initially meets the eye.

Hart has an agenda on Selusa Secundus, andDune: Prophecy’sepisode 1 endingsees him begin to carry it out.

He also exchanged a distrusting glance with the Emperor’s Truthsayer, Kasha, earlier in the episode.

Emperor Corrino also sees Hart survive a sandworm attack, which is a miracle.

Valya Harkonnen certainly isn’t a clear-cut hero.

Set in the universe of Frank Herbert’s Dune series, Dune: Prophecy, a sci-fi epic, follows the political and spiritual struggles on the desert planet of Arrakis. As factions vie for control of the prized spice melange, a prophesied hero emerges, challenging the balance of power and the fate of the galaxy.

With the show being set 10,000 years earlier, why is the tech the same?

While he hasn’t been cast yet, Jason Momoa should return for 2026’s plannedDune: Part 3.

In the meantime,Dune: Prophecycould use some lightheartedness.
