Soldiers of the Kaleesh race cultivated unique forms of martial arts, and one example of these unarmed combat styles, the "Na Jang" philosophy, was incorporated and modified for the purpose of training military forces.
The initial reference to Kaleesh fighting styles appeared in the Steven Barnes penned adult novel, Mace Windu: The Glass Abyss, which was released by Random House Worlds on October 15 of 2024.
