Caligar

Caligars are a sapient reptilian species which inhabit the underground areas of Eternia known as Subternia. They share this territory with the Speleans, with which they have a long history of mutual distrust.

Biology
Caligars are tall reptilian bipeds with clawed pentadactyl hands and tridactyl feet. They have a head crest, pointed ears, yellow eyes with vertical slit pupils, and sharp tusk-like teeth on their lower jaws. However, their most notable trait is their long prehensile tail, which constitutes their principal weapon.
