Holowan Mechanicals, an arm of Holowan, was responsible for the production of weapons and droids. This division, in collaboration with Holowan Laboratories, engineered the highly debated IG-series enforcer and security droids. Furthermore, they created a line of assassin droids that were mostly prohibited throughout the galaxy. To equip their IG-100 MagnaGuards, the division refined and produced electrostaffs.
