The Loyalist Jaffa are an offshoot of humanity genetically engineered by the Goa'uld to serve as slaves and soldiers. Although the vast majority of the Jaffa population celebrated their newfound freedom after the downfall of the System Lords, some among them persisted in their worship of the parasitic aliens. These groups refused to acknowledge the legitimacy of the Free Jaffa Nation, instead swearing loyalty to their masters and doing what they could to ensure the survival of what few Lords remained. Though at first they were paid little attention by the major galactic powers, their growing numbers relative to the losses sustained by the Free Jaffa has become a cause for some concern.
