Threat: Hostile

Last photo of A-17 (IDN) member before decapitation by Noktivagus

Description
Noktivagus is a species of anomalous entity with identical physical characteristics. Each individual has a humanoid base form standing 2.8–3.1 meters tall, covered by a black conical robe with a pointed apex.

The internal body structure is light gray with a non-porous surface texture. Two upper limbs are visible beneath the robe, each ending in two blade-like fingers 20–25 cm long.

Individuals levitate 5–10 mm above surfaces and leave no tracks. Population estimates are unknown. Based on collected data, Noktivagus individuals are territorial and are rarely found within <500 m of each other.

Behavior
1. Nocturnal & Predatory: Noktivagus is active between 00:00–03:00 WIB, targeting solitary humans on empty asphalt roads with visibility <50 m.

2. Solitary: Rarely interacts with others. In 2 incidents where 2 individuals came within 200 m, both displayed avoidance behavior and left the area in <60 seconds.

3. Attack Method: All individuals use the same method: decapitating the victim with their blade-fingers in 2–4 seconds.

4. Post-Attack: The victim’s head is never found at the scene. The purpose of decapitation is unknown.

5. Avoidance: Individuals will cease pursuit if the target enters an area with illumination >2000 lux or a crowded area.

Additional Notes
The solitary nature of Noktivagus is the primary reason incidents rarely occur simultaneously.
