The Ka'hren are a mammalian race native to the planet V'shar. Humanoid in stature, the Ka'hren are isolationists who developed their own forms of space travel but prefer to remain on their homeworld. Any Ka'hren who wishes to leave V'shar has to receive special permission from each of the leaders of V'shar's seven nations. In appearance, the average Ka'hren appears almost skeletal, with tall bodies and thin limbs. Their thick skin ranges in color from blue to dark red to black, and they are hairless except for fur on their forearms and two locks of hair which grow from their temples.
