Jar'Kai
this ancient form of combat used speciallized dueling swords, and involved the use of two swords, one in each hand. This form of combat was originally created by the Yovshin Swordsmen of the Atrisian Empire, who named it after the city on Kitel Phard where they developed it. A similar form of two-handed swordplay was later developed by the Royal Macheteros, who called it Niman. It was this later term that was used to describe a form of two-handed lightsaber combat by the Jedi Order, a technique the Jedi learned from the Legions of Lettow.
