The Nissir gang was the baron Lutz's militia near the border of Geso. The gang, referred to as "the minions of the law" by the baron, was known for raping women and killing cattle which greatly contributed to the fear they inspired in Nilfgaardian citizens. The leader of the gang was Vercta. He met with his friend, Skomlik, the leader of the Trappers and together they coordinated their respective gangs' efforts.
