Lamia

The Laria seem to be human, until you reach their bottom half. They are half-basilisk, with large tails and the ability to inject poison from their fangs. They are part of a subspecies of human, called the Bestia. This makes them related to the Spydric and Lionfolk. Most Bestia are female (excluding Lionfolk)  and resemble humans, but there are some male Bestia. Nobody knows where the Laria came from, but they are seen as deadly creatures.
