Altrusian

Altrusians are a peaceful group of sapient humanoid lizards that are descended from a group of old world Agamidae lizards. Just like lizardmen, they started out of four legged cold-blooded animals, but they evolved into warm-blooded intelligent humanoids that (unlike lizardmen) had completely lost their tails. They originated from Asia, but have spread to all over the world. They are peaceful and gentle to all sapient species and beings, except to vampires due to bloody conflicts with them. They are omnivores that feed on the same food as many other sapient species and sapient beings.
