The Ar'kan system of martial combat is unique to Listhani space, according to Omnet. Utilizing physical techniques of balance, body control, and agility, it is possible to speed reaction times by as much as 300%, even if the sentient is already known to be quick and agile. Psionic abilities are not essential to learning the system, but they are necessary to get the full benefit of this martial art. The Ar'kan system of physical combat is 2100 years old.
