The Lower Shadowlands was a section of the Kashyyyk Shadowlands. It was a very dangerous area that offworlders rarely visited, although a few were known to live there. Around the time of the Jedi Civil War, a group of Mandalorian warriors lived and hunted in the Lower Shadowlands. They only attacked unarmed opponents, and used advanced stealth generators to remain undetected. The great Wookiee warrior Bacca died in the Lower Shadowlands fighting a terentatek, and his Sword blade was lost.
