The Ordo Finitus
The Final Order is the unique belief of the Brotherhood of Dark Jedi, espousing the total domination of the Dark Side of the Force over all life. Including the destruction of the Order of the Jedi Knights.
Many Elders preach about a path to achieving this goal, called the Final Way. There is no strict dogma about the actual process of achieving the Consummation of the Final Way, but the Elders encourage research, exploration, and outright war as a way of acheiving this goal.
