Mara knows the Paparak cross-cut

She stepped close to one of the paintings, lifting her left hand to touch her fingers to the edge of the frame as if holding it steady for examination. Shifting her body slightly so that it blocked the view from both the door and the computer equipment, she placed the tip of her lightsaber against the wall and ignited it.
The snap-hiss sounded about ten times louder than usual. She tensed, senses alert for any sign that anyone else had heard it.
But between Ghent's animated explanation and the increasingly annoying squeal from his equipment, the sound had apparently gone unnoticed. Keeping the handle flat against the wall so that none of the glowing blade would be visible, she eased the lightsaber upward, carefully slicing through the stone at an angle. The Paparak cross-cut was an esoteric bit of engineering technique, one of many the Emperor had taught her over the years, designed to weaken a stressed wall in such a way that it would hold together long enough for the saboteur to safely get clear of the resultant collapse
She finished her cut and closed down the lightsaber. The next cut, she calculated, should be near the base of the support column three meters to her right. Sliding the weapon back into concealment, she moved casually toward the next painting.
A Paparak cross-cut for this size room would normally take no more than five minutes to set up. With the need to look casual about her wanderings, though, it was closer to twenty minutes later before she was ready.
There was one final set of cuts to make. Just to the right of a particularly interesting painting at the back of the room, she stealthily carved out a triangular opening that, once the stone was kicked out, would serve as a quick exit.
And it was time to go.
