Knights of the Elder Sword

The most powerful knights is the human realm and they are the public face that represents the magical community. Under the direction of the magical government Aegis then take out threats to public safety like terrorists, serial killers and rebels. Unlike the Royal Executioners they need permission to mobilize and kill someone as their actions are watched my everyone in the human realm.

Function
Their job is to destroy any and all evil in the human realm. In the past they were an independent organization that struck down anything that could possible be hazardous to the non-magic humans in the realm but now they have lost their autonomy and report to the government and the world royals and instead of being honor filled swords that carry out justice they are more like celebrities and paid mercenaries.
