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.
