Glaucus is a mutation that alters the wings' membrane making it jagged and irregular.
This mutation makes the Kiseilian very beautiful but also less agile and fragile than a common Kise, so they gain -2 DXT and -1 DEF.
The appeareance differs between males and females. You can download the import here.
It is allowed to mod a Kiseilian with Glaucus mutation by applying jagged membrane on other body parts, for example on the leather like tails (Brush).
