Two and a half centuries after their founding, the inhabitants of the Nanocodax civilization of NUVAGAIA show in their physique the demands of a highly technologized underground environment in symbiosis with artificial intelligences. Their bodies display subtle adaptations and integrated enhancements, the result of transhumanist engineering and nanotechnology.

The human body is a canvas in constant update. Some have photosensitive skin that emits notifications, others have integrated microstructures that turn body language into executable code.

Build and Posture

• Moderate height and weight: heights between 1.60 m and 1.75 m, with a body mass index optimized for metabolic efficiency in confined spaces.
• Compact build: proportionate torso and limbs, with defined but not exaggerated musculature, favoring agility in tunnels and narrow passages.
• Stable posture: spine slightly reinforced with biomechanical nanofilaments, providing structural support when interacting with artificial exosystems.
• Skin and covering: subtle tattoos of luminous circuits on their skin; a dermis with micro-layers that reflect bluish light, improving recognition in the dark and reducing visual fatigue in low-light environments.

Facial Traits

Skin, Texture and Tone

• Pale tone with metallic highlights: variations ranging from ivory to light grey with silvery gleams, integrating nanopigments that filter infrared radiation.
• Smooth surface with microchannels: microscopic grooves on cheeks and forehead that channel secretions of reparative nanomaterials, activated after minor damage.

Eyes and Gaze

• Synthetic iris: cool shades (gunmetal grey, steely blue), with interface implants that project data directly into the nervous system.
• Round, variably adaptive pupil: able to dilate in seconds to enable vision in the dark.
• Reinforced ocular rim: protein microfilaments that cushion impacts and minimize moisture loss, compensating for their low-frequency blinking.

Hair and Integrated Details

• Short hair: practical styles with interwoven conductive fibers that transmit biometric data.
