The battle was joined, but Kacela felt something else ahead...in the room where the Sith were focusing their efforts on some kind of ritual. Invisible to the eye, the Force loomed large there like the black anvil atop a thunderhead. To the Jedi, the power of the Dark Side seemed unassailable...but she had learned something of its nature in her dealings here. The Dark Side had great power, but it had a subtle weakness as well. Its strength was easily turned against itself. Lust for power, fear and hate, these things drove it and its acolytes to consume themselves in their constant quest to be atop the heap.
Kacela reached out with the Force. She didn't think she could simply bludgeon the ritual into failing...but perhaps she could introduce small, carefully measured disturbances. The kind of disturbances that might be made if, say, one of the Sith were trying to take control of the power by themselves. Hopefully their own paranoia would do the rest.
(Using the Force with a Force Point to affect ritual; Force Boon lets me spend potentially 2 FP on an action though. With GM permission I'd like to spend another FP to add to the roll.)
Use the Force: [roll0]
Force Point (if allowed): [roll1]
