Cut Scene[]

The camera sees Fort Knox. Under the screen the words Fort Knox, KY and 6:43:15 appear. The camera zooms into the building. You see the Lucian vault open. The camera moves into it, and it searches first to the left, and then to the right. There is an orange pot with dirt in it. The camera zooms in, a four leaf clover grows out, and the camera zooms into the plant, with the screen growing black, and the word CLOVER appears.
