Heliass

Heliass is a fictional planet featured in the science fiction novel "Dune" by Frank Herbert. It is not a primary setting in the main series but is mentioned in supplementary materials and can be considered part of the broader Dune universe. Heliass is described as a world that experienced significant environmental challenges.

The planet is known for its harsh climate, characterized by extreme temperatures and arid conditions. This environmental hostility has shaped the limited life forms and civilizations that inhabit Heliass. Details about its inhabitants and their specific societies are scarce, often serving as background context rather than central plot elements.

In the context of the Dune universe, planets like Heliass often serve to illustrate the vastness and diversity of worlds within the Imperium, highlighting different approaches to survival and societal development in the face of environmental pressures. The mention of Heliass contributes to the rich tapestry of Herbert's fictional galaxy.
