"Operation Shadowfall" was a TOS roleplay module for FASA's Star Trek: The Role-Playing Game. It was the fifth of eleven licensed adventures published in FASA magazines, this one in Stardate Magazine vol.2 #8, and was co-written by Blaine Pardoe and Dale L. Kemper. This sequel to TOS episode & Star Trek 4 novelization: The Enterprise Incident involves intrigue and sabotage after Starfleet reverse engineers a stolen Romulan cloaking device and begins testing prototypes aboard Federation starships.

Description[edit | edit source]

This short scenario is designed for use with the USS Merlin (NX-607), a Wizard-class vessel. The players are the members of the ship's security section during the second attempt to test a Federation cloaking device. Considering the outcome of the first such test and the destruction of Merlin's sister-ship Sparrowhawk, security is intended to be very tight.

Summary[edit | edit source]

Starfleet physicists reconstruct a cloaking device based on the one stolen from the Romulan Empire by the USS Enterprise in 2268, which had become inoperable during its acquisition. An antidote is developed to counteract headaches caused by exposure to the device. The USS Sparrowhawk successfully tests the device while unmanned, but Sparrowhawk's antimatter integrity is sabotaged during a manned test. 15 officers are able to beam off to an escort ship, but 12 are killed when the vessel explodes.

USS Merlin is subsequently prepped for follow-up tests. Merlin engages its cloak while at warp five, accompanied by the Nhat-Le. During a planned voyage to the Delta Zeta system, the ship's security chief is severely injured after being knocked unconscious and falling down a Jefferies tube. Since the cloak blocks communications, the ship's CO sends the escort an update about Tarrow's condition via a navigation beacon, then orders his security officers to track down the attacker and capture any saboteurs.

Subsequent events depended on game play, including whether the players can expose Klingon and Romulan spies, locate a bomb, and keep Merlin from being captured.
