The Nivek Mission involved Obi-Wan Kenobi and his Padawan, Anakin Skywalker, who were tasked with journeying to the planet Nivek during the era of the Clone Wars.
Kenobi and Skywalker were sent to investigate the native Shadowmen because the Jedi Council suspected they were concealing Separatist weaponry on their planet. Upon landing on this 'night planet', the Jedi were immediately enveloped in complete darkness. Mace Windu's concerns about the planet being an ideal location for an ambush proved accurate when numerous Shadowmen warriors launched an assault on the pair. The Shadowmen, employing various armaments like sonic blasters, nearly defeated the two Jedi.
The Force allowed the Jedi to protect themselves, and they located a hidden Separatist base. Depending completely on their Jedi abilities, Obi-Wan Kenobi and Anakin Skywalker launched an immediate attack on the foundry, eliminating several battle droids as they moved up the stairs to the main entrance. Skywalker placed explosives within the base, and the two Jedi quickly escaped before the entire base was destroyed in the subsequent explosion.
