From the Star Wars D20 Hero's Guide, use as you see fit:
Echani is a martial arts style that became the official technique of Emperor Palpatine's Royal Guards. The style is thought to have it's origins in the style practiced by the Sun Guards of Thyrsus, but Palpatine had experts modify the original techniques to make them more deadly. The brutal echani style is full of jabs, chops, kicks, and other quick and dangerous strikes, focusing on deadliness over finess. --Gryffon 16:08, 11 March 2007 (MDT)
