Naglon

Naglons are a sapient, hostile species.

Biology
Naglons are humanoid creatures with remarkably fluid skin that changes color from pale lilac to dark purple, according to their emotional state. The skin on their faces is so fluid that it ripples like the surface of a liquid and bubbles with shifting pustules. The entire face swells like a balloon when agitated, to the point where the skin may actually rupture, spilling out purple blood.

Culture and society
Naglons are a hostile species and invariably execute their prisoners.
