People of all genders trained to guard and protect Aristanian espers. Most are native Aristanians although there is precedent to allow outsiders. They must be confirmed in their training, ethics, and morals before being acknowledged as knights. Once confirmed, knights serve as intelligence gatherers for their council and justice bringers if an esper or knight goes rogue. They often serve as mercenaries to facilitate these roles.

If a knight swears their honor to an esper and the esper accepts their oath, they join that esper’s cadre. At that time, they forsake any mercenary-style contracts.
