Species & Entities
Catalogued non-human intelligences reported in encounter records across decades and cultures. Each dossier aggregates physical description, classification, intelligence assessment and witness correlations.

Small humanoid (1.0–1.4 m) with smooth grey epidermis, large oval black eyes, no visible nose or ears and a slit mouth. The most frequently reported NHI in modern abduction-class narratives. Often reported wearing form-fitting blue or grey jumpsuits.

Intermediate morphology presenting both human and Grey-class characteristics. Reported in late-20th- and 21st-century abduction-narrative literature as an apparent product of recurring multi-generational interaction programmes.

Energy-Based Intelligence presenting as a luminous, non-corporeal form. Reported across millennia of religious, spiritual and witness literature as a guiding, protective or messenger presence. No solid biological form; manifestations are described as radiant, often warm in hue.

Tall (2.1–2.7 m), insectoid-form bipedal entity with mantis-like morphology, large bulbous wraparound eyes, extra folded manipulator limbs and additional lower-leg articulation. Reported in witness narratives as a scientist or overseer presence, frequently in coordination with Grey-class entities.

Tall (1.8–2.2 m) human-appearing entities with fair complexion, light hair and blue eyes. Reported across European and contactee-era literature as serene, articulate and physiologically near-identical to humans.

Tall (1.8–2.4m) bipedal reptilian humanoid frequently described in witness accounts. Scaled epidermis, vertically slit pupils, prominent brow ridge and elongated digits. Reported associations with subterranean facilities, military installations and apparent leadership/oversight roles in human-NHI interaction reports.

Humanoid silhouette presenting as an absence of light. Reported across global folklore and modern witness corpora as a dark presence frequently associated with fear responses, environmental anomalies and sleep-state encounters. Characteristics below are witness-reported and remain unverified.

Elongated humanoid (2.0–2.5m) with human-derived bipedal morphology, enlarged cranial structure and large forward-facing eyes. Frequently reported in leadership/coordinating roles during Grey-class encounter narratives.
