A crow launches out of the darkness, moving so quickly that it becomes a sharp spear of darkness. In the same moment that Jasper is pulling Lapis free, the blade pierces her body. It sticks in her body for a painful few moments, before her physical form will give way.

Her orange gem falls to the floor, side by side with the lapis lazuli.

"Well, I never," the Lady gasps.
