Vemousian Dragon Subspecies of the Aracon Dragon.

Known for living in the crystal caverns located in the Valley of Birth. Their distinct glow comes from bacterial colonies within their blood that is bioluminescent. The Bacteria form crystalline colonies within the cave and after generations of consumption of cave wildlife, Vemousian dragons, developed a symbiotic bond with the species. The Baterial colonies are unique enough that lineages can be decerned by the colony's glow and intensity.
