Nulkoons

Nulkoons are a fictional species originating from the planet Xylos in the K'tharr system. They are a silicon-based lifeform, characterized by their crystalline exoskeletons and a unique bioluminescent internal structure that pulses with light. Nulkoons possess four limbs, each ending in three sharp, prehensile digits. Their heads are largely featureless, with two large, multifaceted eyes that can perceive a broader spectrum of light than humans.

Communication among Nulkoons is primarily through a complex series of light pulses and subtle vibrations emitted from their exoskeletons. They are known for their advanced understanding of geological and energetic phenomena, often described as "earth-singers" by other species due to their ability to manipulate and harness planetary energies. Nulkoons are generally a solitary and contemplative species, preferring to observe rather than actively interfere in galactic affairs. Their lifespan is significantly longer than that of carbon-based lifeforms, with individuals capable of living for several millennia. Their reproductive cycle is slow and tied to specific planetary alignments, making them a relatively rare species.
