Holowan Laboratories

Holowan Laboratories was a manufacturing company active during the Clone Wars that created battle droid models, including the IG-100 MagnaGuard, IG-86 sentinel droid, and IG-RM bodyguard and enforcer droid. Following the conflict's resolution, the company was able to evade the Galactic Empire's ban on the production of battle droids by reclassifying their products as security droids.
