The Nulvoxi, a race of giant insectoids they call the tunnels of Pathos their home! Using the maze of tunnels and rivers of free flowing Lazarus to traverse the underbelly of the planet, they are rarely seen on the surface. As a hive-mind race, they are able to communicate telepathically, but they also have a vocal sac located in the thorax. They use this to communicate with the other many races that call the Ley Lines their home, like the Machina.

The Nulvoxi, are one of the few races that can crystalize Lazarus without the need for technology. They use this crystalized Lazarus to create their large city structures, as well as their armor and weapons. This extended contact with the substance, has given their bodies and bioluminescent glow, and colorful pigmentation. As an isolationist race, they don't seek help from other races, nor do they need it. The Machina have learned that trading with them is futile, as any Lazarus they give them, they will only take and not give anything in return.

The Alchemist, at the Mages Guild of Eibon have yet to make contact with the Queen, only ever coming into contact with workers, and on occasion Soldiers. So not much is known about this race, information is being slowly traded with the Machina, as they are in close proximity to what would be considered the capital of the Nulvoxi.
