Physiology
The Neron are tall, lean, and muscular with long torsos, long arms, and shorter legs. They often reach over 7 feet in height but appear to take several decades to mature. Their skin is pale brown. Their hair is silver-orange. Gilled structures appear on the neck and forearms, partially functional in the vent environment where moisture and toxic gas mix in concentrations that would kill anything breathing through lungs alone. Their fingers carry setae, fine adhesive filaments that grant grip on wet stone and submerged surfaces. These are the same anatomical markers found in Rupturan remains. In the Rupturans, they are archaeological evidence. In the Neron, they are still in use. The ruins they inhabit sit near the coasts of Kela's largest geothermal water systems, and their bodies are built for an existence that moves between air and water in a way that no other living population on the planet can replicate.
Behavior
The Neron live in ancient ruins built by ancestors whose capabilities have been lost through devolution over an unknown number of generations. The ruins are extensive, architectural, planned. Someone built them. Someone with foresight and engineering capacity. The current population crafts basic clothing and weapons from local materials and can learn simple Geban language but cannot produce complex speech. Solitary Neron flee from encounters. Groups defend their territories aggressively and function as apex predators within their vent ecosystems, controlling the fauna that inhabits the geothermal corridors.
Devolution
What caused the decline is not recorded and may not be recoverable. Prince Daer studied the question and speculated in his journals that if caloric scarcity persisted across enough generations, if selection pressure favored brute survival over abstract planning, if those who could think ahead were not the ones who reproduced, regression becomes a mathematical certainty. The Neron are what remains when that math runs long enough.
Regeneration
Prince Daer conducted experiments with the Neron through the Jeyrhan Bio-Engineering Consortium and the Kela Maritime Guild. The results included reliable limb regeneration and accelerated recovery from wounds previously considered fatal. The Neron's biology, despite its devolved state, retains regenerative properties that no other humanoid population on the planet possesses. Whatever their ancestors were, this capability survived the decline.
Ancestry
The silver-orange hair is a phenotypic marker shared with the Northern Pass Ngorrhali and the historical Thaloryn population. If these are connected, the common ancestor predates recorded history and likely traces to the Rupturans. The Neron may be the closest living link to whatever the Rupturans were before their extinction, preserved not through strength but through isolation in an environment no other population wanted.
