Pegmaatissa
Pegmaatissa is a fictional species originating from the planet Xylos in the Andromeda galaxy. These beings are characterized by their bioluminescent skin, which shifts in color and intensity to communicate emotions and social status. Pegmaatissa possess a unique physiology, featuring a dense, crystalline bone structure and a four-chambered heart capable of pumping a nutrient-rich, oxygen-carrying fluid throughout their bodies. They are known for their symbiotic relationship with the flora of Xylos, particularly the phosphorescent mosses that grow on their home planet. This moss provides them with a primary food source and contributes to their own bioluminescence.
Socially, Pegmaatissa are organized into communal hives, where decisions are made through a collective consciousness facilitated
