The Sek are a species created by Yari Litten Ve'Rek.

The Sek are a mostly bipedal, fur-covered species. Their skull shape is similar to that of an earth Mustelidae, with a longer muzzle and movable quadrate bones similar to Order Squamata. Their teeth consist of fine-pointed canines. Four ears provide excellent directional hearing, and each Sek possesses two pairs of eyes. Their tongues are thin and ribbonlike, nearly reptilian, as are their long, thick tails. Two rows of sharp, keratinous quills line both sides of the base of their tails, usually black in color. The largest of these are located directly at the base. All limbs are perfectly articulable, with the feet possessing three fingers and two thumbs.
