Form DCLXVI: Atra-Manua or the Way of the Black Hand, the Art of the Black Hand (simply known as Atra to its practitioners) was the primary lightsaber form for the Hand during the Successors War. Despite it's relatively short history, Atra-Manua had an immense affect on the history of the galaxy during the Legacy and Unity era's. Many considered it somewhat unbelievable that, not only was Atra-Manua a defensive form, but that it was a defensive form created by Jasca Ducato.
