"The Tunnel" served as the defensible entrance to Moonbender Colony. Located within a tower, its walls were magnetically sealed so that the Remainders—former bounty hunters who managed and defended the colony—could angle their blaster fire and make it impossible to block. When the Sith apprentice Darth Maul attacked the colony, he entered the tower through the Tunnel. Despite the attempts of General Zandloss and several other defenders, Maul was able to make it through the blast tunnel and breach the rest of the colony.
