Spelean

Speleans are a sapient species of winged chiropteran humanoids which inhabit Subternia: the underground areas of Eternia. They share their territory with the Caligars, with which they have a long history of mutual distrust.

Biology
Speleans are bipedal bat-like creatures with six limbs: two legs, two arms and two wings. They have blue skin, red eyes, a jagged mouth, clawed feet, and fangs on their lower jaws. Their ears are large and give them acute hearing.
