Darmians

Darmians are a fictional species featured in the science fiction novel "Project Hail Mary" by Andy Weir. They are an alien race encountered by the protagonist, Ryland Grace, during his mission to save Earth. The Darmians are described as intelligent, technologically advanced, and possessing a unique physiology. They are naturally bioluminescent, emitting light from their skin, which serves various purposes, including communication.

Their home world, which Ryland Grace refers to as "Tau Ceti," is characterized by a dim atmosphere and a high concentration of Astrophage, the microscopic organisms threatening both Earth and the Damian homeworld. The Darmians have developed sophisticated technologies to combat the Astrophage, including specialized ships and equipment designed to harvest and utilize the energy produced by these organisms.

Communication between Ryland and the Darmians is initially a significant challenge due to their vastly different biological structures and sensory perceptions. However, through a process of mutual learning and adaptation, they develop a means to understand each other, enabling cooperation in their shared struggle against the Astrophage. The Darmians are depicted as a species driven by a strong sense of survival and a deep understanding of cosmic phenomena. Their interactions with Ryland highlight themes of interspecies collaboration, the universality of scientific principles, and the courage required to face existential threats. They are presented as a benevolent species, willing to share knowledge and resources to ensure the survival of other intelligent life.
