Would you break the rule of Two?
You're the most powerful in the dark side of the Banite sith. You're middle aged and have mastered all of the techniques/powers, lightsaber forms, and abilities that you learned from your master. But you feel that in your age, you couldn't possibly teach all of your knowledge to one pupil. Knowing that you've reached the apex of Bane's line, do you keep in the tradition of your predecessors or would you take two pupils to maximize the skills of the Sith traditions?
How would you prevent your students from trying to kill you? And what characteristics would you look for in your students?
