CAPTAIN'S LOG, SUPPLEMENTAL — In a state of severe shock, Mr. Spock has been permitted to beam back aboard the Enterprise - the rest of the landing party and I remain stranded on Heartland. I am convinced that the only person who can help us is Jacob Kell, the man we came here seeking. His years spent alone here have made capable of somehow communicating with whatever force rules this planet, the force that has struck down two of my crewmen...the same force that drove all but one of this planet's original 100 colonists completely insane.
