Based on another a chat I had with a friend; Vorepone’s hidden eye (resembling that of a snake’s)* acting as her “thermal vision”. Super sensitive to heat, she can use it to track after prey that don’t do well in hiding themselves, aiding in getting around in the dark or even “seeing through” up to a few thin layers of heat-conductive material.
 
(But due to her using one eye most of the time, she has problems sensing depth.)
 
Gotta practice with my tablet! First colored piece I’ve worked on so far. Here’s to many more.~
 
*(Yes, I know that snakes are blind and sense heat through pit organs rather.)
