The Jesters (ジェスター猟兵団) were a jaeger corps active in Zemuria in the early 1200's. They operated primarily in the peripheral states along the Erebonian border. They became infamous when in early 1202 they reemerged after six months of absence and launched a series of attacks on the branches of the Bracer Guild all across Erebonia. This action devastated the guild but it also drew the attention of Cassius Bright, who with the surviving bracers and the cooperation of the Imperial Army hunted down the Jesters and captured or killed almost all of them. This incident was ultimately a plan by Ouroboros to draw Cassius out of Liberl, orchestrated by Campanella, to whom the Jesters were merely a catspaw, and briefly trained by Loewe under his alias Lorence Belgar to better maximize their utlity.
Following the incident, the Jesters effectively ceased to exist though remnants of the group would continue to cause trouble for some time.
