The Shadowmen were a race of humanoids who originated from Nivek, the "night planet".
Renowned for their prowess as hunters and trackers, the Shadowmen were fiercely protective of their territory, leveraging the darkness of their planet to launch ambushes. As technologically advanced hunters, they utilized sonic blasters along with durasteel cable netting in order to ensnare their prey.
During the era of the Clone Wars, the Shadowmen formed an alliance with the Confederacy of Independent Systems, permitting the Separatists to establish a weapons manufacturing complex on their homeworld. Approximately four months after the war's commencement, Obi-Wan Kenobi together with Anakin Skywalker embarked on a mission to Nivek with the objective of destroying the facility, during which they were assailed by the planet's inhabitants. Despite the inability to visually perceive their adversaries, the Jedi employed the Force to detect the Shadowmen, ultimately succeeding in their mission.
