Nebuloiden

Nebuloiden are a fictional species that appear in the science fiction novel "A Fire Upon the Deep" by Vernor Vinge. They are a non-biological, crystalline lifeform native to the Tines' World. Nebuloiden are characterized by their complex, multi-faceted crystalline structures and their ability to communicate through telepathic resonance. Their existence is tied to the unique environment of their homeworld, which has a very low concentration of certain elements essential for biological life.

These beings do not reproduce in a biological sense but rather grow and fragment, with new Nebuloiden forming from existing ones through a process not fully understood by other species. Their intelligence is vast and ancient, and they possess a deep understanding of the universe, often contemplating philosophical and existential questions. Nebuloiden are generally peaceful and introspective, preferring observation and contemplation over direct action. However, they are not entirely passive and have been known to intervene in galactic affairs when they deem it necessary, using their unique abilities to influence events from afar. Their crystalline nature makes them incredibly resilient but also vulnerable to certain forms of energy.
