The Thyrrus are a squid-like alien species who see war as a performance.


Thyrrus's are adapted to survive in atmospheric, gravitational, and geographical extremes. Possessing four forearms each triple-jointed with simple fingers with limited dexterity. Their lower tentacles are capable of massive strength and dexterity providing acute manipulation. Four eyes with 230-degree peripheral vision. Forward pair allow them to see in infrared, while the rear pair are extremly photosensitivity. Lacking an exo-skeleton, they are instead supported by a cartilaginous central column.

They absorb nourishment through a form of osmosis by through their mouthparts that can absorb from almost anything. Their respiratory regulation is similar, providing a type of built-in organic gasmask. The Thyrrus can also change colour and surface texture at will, though they often displaying gaudy patterns and clashing hues rather than camouflage.


Having no concept of victory or defeat, the Thyrrus see wars and day-to-day business as a vast performance.
