The Tingel Arm Sieges were a series of moves made by the Shadow Imperium's 1st Assault Fleet and Morgukai Shadow Army against the Galactic Empire and local governments along the Tingel Arm between Imperium space and the Unknown Regions. The purpose of this series of raids were to spread Imperium influence throughout the Tingel Arm, and to provide a larger foothold on the eventual moves of both the Shadow Imperium and the Sith Brotherhood.
