Episode 3b "Ghosts of Conscience" (FASA)
STARDATE 2301.15
    Curp and the crew of the Essex are ordered to rescue the USS Hood, which has turned up missing. The Hood was conducting a top secret mission for Star Fleet Intelligence, investigating a natural phenomenon of two rotating neutron stars and how they affected the area of space around them. Along with these orders came an encapsulated packet meant only for the Captain to be read en route. Without haste, Curp ordered the Essex to intercept the Hood. The encapsulated message contained more detailed information on the Hood's mission.
    The USS Hood was sent to investigate an anomaly known as a space time interphase (see TOS episode "The Tholian Web"), and record its findings so Federation scientists can try to duplicate the effect under controlled conditions for further study. The effects of the interphase interfere with normal brain functions and induce a madness condition. A remedy for this effect had been included with the message for the Doctor to reproduce and dispense amongst the crew. A greater dose will be required for any landing parties. Curp is ordered to retrieve all the data files from Engineering, Medical, Life Sciences, Physics, and Chemistry departments on board the Hood. Command code overrides to open and retrieve the files were included in the message. Based on the data retrieved from the Hood's message buoy, it's unlikely that there will be any survivors, but, if there are, the orders goes, that they are considered expendable. Once the landing parties retrieved all the data, the Essex is to destroy the Hood for security purposes.

   As the Essex approached, gravitational stresses rock the starship. They soon discover that their very presence affects the gravimetric distortions immediately around them. Curp orders a more cautious approach to the Hood to avoid further damage. Sensor scans showed the USS Hood exists only intermittently in this space. Barlok's analysis projected that the Hood should remain relatively stable for the next 5 hours, however, the Essex's very presence near the Hood affects the gravimetric distortion. He concludes that once a landing party beams over, the Essex should move away to eliminate the chance of the Hood phasing out unexpectedly while the party is on board. Communication Officer Oneda reports that communications between the two ships will be cut off due to the gravatic distortion. Curp organized a six person landing party consisting of himself, Barlok, Dr. Heronomous, and two security officers. They were to beam down, recover the data and wait for the Essex to return and retrieve them in 5 hours.
    The landing party materialized onto the bridge of the Hood. A thin layer of smoke filled the room, stemmed from the broken, and burnt control consoles. Several bodies lie on the floor, the remains of a ghoulish frenzy that gripped them in the final hours. Dr. Herronomous concluded that they killed each other with whatever was available, and eventually died of their injuries. It was noted that not all of the bridge crew were present. A chair protruded from the main computer console at the science station. Barlok, chair removed, managed to reactivate the console and retrieve the ship's sensor log into his tricorder. He notes that turbo lifts are inoperable.
    They make their way through the ship by stairs and gangways. While heading towards the Special Studies Lab, the group is assaulted by crewmen who've materialized back into this dimension! Stricken with the madness, the crewmen claw at the landing party members, dragging several of them down the stairs. The melee continues until the crewmen fade once again.
    In the Special Studies Lab, the landing party learns the truth about the Hood's mission:  Star Fleet Intelligence wanted to use the interphase effect as a potential weapon to make entire ships -- and crews-- disappear from the space/time continuum!
    The party continued on to the Engineering section, only to find it sealed from the inside. The security detail used their phasers to burn through the door. Barlok noted that the phasers disturb the delicate spatial balance, and that caution should be exercised when using them.  The door was barricaded from within, apparently by the room's sole occupant: Captain Hugo Revere, whose body is slumped over the main computer console. On closer inspection, the Captain held a computer tape in his hand. Removing the tape, Curp played it. On it was the Captain's final log entry.  He explains how he jammed the door after the crew went mad and kept the impulse engines active in hopes that whoever comes to retrieve the data would find the ship operational. To make sure that his madness wouldn't undo what he had done, he took his own life with a batch of poison from the ship's medical stores. His final words were a cryptic accounting of the cost of lives this mission has had and how many more to come should the weapon be built.
    The landing party continued to retrieve the remaining data. Acquiring the remaining files, the group set out for the bridge to await their beam out. While going up the stairs, another set of crewmen materialize and attack! Time running out, the landing party feverishly try to dispense with the attackers before their departure window disappears. Phasers ablaze, the phantoms scatter, however, the fire fight destabilized the area of space around them, and when the crewmen disappear, so does Barlok! Curp orders the group to continue onto the bridge. At the appropriate time, the group beams back to the Essex.
    Back on the Essex, the crew watches as the ship fades, and then disappears from sight. Desperately, Curp and crew try to determine the ship's next reappearance in hopes to beam back Barlok from his last known location. One hour later, they're ready to attempt to bring him back. The transporter strains to find anything to beam over. The first attempt failed. Adjustments set, they try again, with success! Barlok appears onto the pad, none the worse for wear, and just in time as the bridge reports that the Hood has faded once again, this time forever.
