pengéi

Pengéi refers to a fictional species originating from the planet Xylos in the "Stardust Chronicles" series. These creatures are described as sentient, silicon-based lifeforms with a crystalline outer shell. Their physiology is adapted to Xylos's high-gravity, low-light environment, allowing them to navigate treacherous terrains with remarkable agility. Pengéi communicate through a complex series of resonant frequencies emitted from internal organs, which can be perceived by other species as a form of telepathic exchange.

The Pengéi society is characterized by a deep reverence for geological formations and an intricate understanding of Xylos's mineral resources. They are known for their advanced metallurgy and their ability to manipulate crystalline structures for both practical and artistic purposes. Socially, Pengéi are organized into communal "geodes," each governed by an elder council chosen for their wisdom and mastery of geological lore. Their culture emphasizes patience, long-term planning, and a profound connection to their planetary home. Conflicts are rare and typically resolved through philosophical debate and resource allocation rather than physical aggression. Their interactions with other species in the "Stardust Chronicles" are often cautious, driven by a desire to understand and preserve their unique way of life.
