"See my shadow changing,
Stretching up and over me.
Soften this old armor.
Hoping I can clear the way
By stepping through my shadow,
Coming out the other side.
Step into the shadow."

Some female Talkani have the power to shift into a feral form when threatened. These females are called Panahasi, and Yso is one of them.
