Legend
That's similar to my theory.Basically Jedi masters visions lead them to murder Padawans. One of the masters was a Sith.
As infants, Mae and Osha are hidden from the jedi recruiters by their parents. Several years later the jedi have a vision of a force dyad of tremendous destructive power. Four knights are dispatched to take the children into protective custody (not to kill anyone) before they can harm anyone. The parents are not willing to let the jedi take the children, and a fight breaks out. This triggers the children to release their destructive power (Force fireball), and the parents (and others?) are killed. The jedi separate the twins to prevent it happening again, each being told the other was dead. Sol takes charge of one, Indara the other. Torbin attempts to deal with his guilt through meditation; Kelnacca goes into self-imposed exile (echoes of Yoda and Jolee Bindo here); Indara blames the jedi order, and sets out to destroy it (she is the "Kreia" character).
The sith give things a little nudge here and there, but they largely let the jedi destroy themselves.
