The Petra domesticus is a cryptic and controversial subspecies thought to have emerged through a prolonged sedintary lifestyle. Compact, ovate, and completely motionless, P. domesticus is most notable for its high mineral density, complete lack of metabolic activity, and unmatched emotional stability.
Though lacking appendages and internal organs of any kind, Petra domesticus is considered highly loyal, never leaving its parnter's side unless forcibly moved.
This species can be found almost anywhere in Atalav. It displays remarkable adaptability, thriving in both sun and shade, solitude or social settings, silence or music. It does not eat, sleep, move, or die (under ordinary circumstances).
Due to its perfect emotional insulation, they are banned from gambling halls in Veritam.
