Form VII, also known as Juyo, the Way of the Vornskr, or the Ferocity Form, was the seventh of seven forms recognized as canon for Lightsaber combat by the last Jedi Council of the Old Jedi Order. In use, millennia prior to the Battle of Yavin, the Juyo incarnation of Form VII was described as the most vicious form of Lightsaber combat and was said to involve significant internal focus on the part of the user. Juyo had many practitioners throughout the years, including Jedi Masters Kavar, Zez-Kai Ell, and Vrook Lamar. As time passed, knowledge of Form VII became restricted among the Jedi Order, whose members were worried that its precepts would lead practitioners toward the dark side. In contrast, members of the Sith, such as Darth Maul, employed Juyo without reservation, as did Dark Jedi such as Galen Marek.
In the later days of the Galactic Republic, a new variation of Form VII, dubbed Vaapad after a creature native to the planet Sarapin, was created by Jedi Masters Mace Windu and Sora Bulq. Vaapad was explained as being a state of mind rather than just a fighting style, allowing the wielder to channel his own inner darkness into the duel, and accept the fury of the opponent. Windu, Bulq, and Windu's Padawan Depa Billaba were three notable practitioners of the Vaapad variant. Records of both Juyo and Vaapad survived the Great Jedi Purge and were recovered by the New Jedi Order, who preserved the records of Form VII into the Sith–Imperial War.
