Glykan

Glykan is a hypothetical planet featured in the novel "Dune" by Frank Herbert. It is not a primary setting like Arrakis or Caladan, but it is mentioned in the context of the Imperium's history and political landscape. Glykan is described as a world that underwent significant environmental transformation, shifting from a lush, fertile planet to one facing a severe ecological crisis. This transformation is often used as a cautionary tale within the "Dune" universe, illustrating the potential consequences of unchecked industrialization or environmental mismanagement.

The specific details of Glykan's history and its inhabitants are not extensively elaborated upon by Herbert. Instead, its mention serves to broaden the scope of the "Dune" universe, hinting at a vast galactic history with diverse planetary experiences. The ecological struggles of Glykan are implicitly contrasted with the more extreme, yet managed, desert environment of Arrakis, highlighting different approaches to planetary survival and resource management within the Imperium. Its ecological decline underscores the fragility of planetary ecosystems and the importance of understanding and respecting environmental limits.
