Guest Stars:
- Commander Muafo: Commanding officer of the Akaru flotilla.
Recently-established subspace communications with Setu, the homeworld of the Akaru, have suddenly ceased. It appears to be due to a pulsar deeper within the Expanse, giving off interfering radiation. Given our diplomatic experience with the Akaru, we have been sent to restore the connection.
Captain’s Log: Stardate, 51445.6
Plot: The crew uncovers a VinShari plot to raid the Akaru homeworld under cover of an interstellar disaster.
The ‘A’ Plot: Contact has been lost with a subspace communications relay station near Setu, homeworld of the Akaru. The unmanned station helps enable real-time communication with the isolated culture, and the Lexington is sent to investigate as the crew has experience of working with them.
As they get closer, Zepht analyses the last signals received from the relay. He identifies a distinctive squawk, occurring as the signal ends, as characteristic of the subspace element of a pulsar emission. This kind of event could rapidly overload even shielded subspace radio equipment, but the nature of pulsars means that it couldn’t be a random occurrence. The Corps of Engineers would never have placed the relay in the path of a pulsar beam, so something must have caused the pulsar itself to shift its axis of rotation. Which is impossible, except possibly with Tilikaal-level technology.
Approaching the station location, the sensors pick up half-a-dozen ships positioned on its far side, and they do not respond to hails. Interpreting the captain’s orders a little creatively, Quinn drops out of warp to one side of the station, skewing to a hard stop and surprising the other ships, which turn out to be a squadron of Akaru frigates. Their weapons are active, and Raynor reports a communication from the squadron’s commander, Muafo, warning them not to make any sudden moves. Requests for explanations are ignored, and sensor scans of the surrounding region show nothing out of the ordinary.
Detailed scans of the relay station itself show it is dark, its fusion core running at sustainment levels, but with no power being used elsewhere. There are no life signs and no indications of external damage.
Taking a toolkit, Azonan beams across to investigate. He finds the station is pleasantly (for an Andorian) cold, but that it retains a breathable atmosphere. There is no power available to the consoles, and tracing the EPS system shows that a conduit is blocked. He clambers down an access tube to the fusion plant, burning his hand as he cuts off the power so he can make repairs. Returning to the damaged conduit, he finds that it has been crushed by some kind of mechanical device.
Outside the station, the Akaru vessels begin to manoeuvre, apparently repositioning themselves to better watch for trouble from the anomaly-ridden regions to either side of the spacelane. The command vessel moves cautiously past the station, putting it on a path towards the Lexington. Konin asks his crew to be alert, and Raynor to prepare for a possible tight-beam communication. It appears the Akaru commander has the same idea: as his ship gets closer, it shines a communications laser at the Lexington.
Once a channel is established, he explains that Setu has recently come under attack, a powerful subspace energy beam suddenly sweeping across the system, wiping out communications and disabling their data network. The subspace communications link with Starfleet went down shortly afterwards, convincing many of the Akaru’Bak that this was a precursor to invasion, possibly by the VInShari. Some of them were worried that the VinShari were in league with Starfleet. Konin explains about the suspected pulsar re-alignment, and that it may be related to Tilikaal activity, rather than a VinShari weapon.
On the relay station, Azonan has replaced the conduit, and taken the damaged section up to the control room. He examines the damage in detail while waiting for the systems to come back online, finding traces of an unusual metal alloy. He scans the room with his tricorder and finds more traces of the metal near the airlock door. A closer look shows that the airlock itself is open to space, the outer door having been ripped out of its housing. Straining to see through the porthole, he sees a deep gouge in the floor, which may have been made by a VinShari harpoon.
Then he hears a noise from the corner of the room, and realises that the shadows there are darker than they should be. His tricorder doesn’t show anything out of the ordinary, but then a figure emerges from behind a console, a VinShari enforcer. Azonan, unarmed, desperately calls for assistance, but the combadge is being jammed. The enforcer approaches, but then disappears as a VinShari woman emerges from thin air to one side and attacks him. He swings his toolbox at her, then takes a more defensive posture as she attacks again. On the Lexington, Raynor and Zepht have managed to connect to the station’s internal video monitors, and they are able to beam the engineer out before he is injured.
Konin, Azonan and Raynor arm themselves with phaser rifles and return to the station, but despite intensive scanning are unable to locate the VinShari. Azonan notes that she appears to be a Midajah-Ka, with holographic projection equipment, and wonders if the phaser sweep protocols developed for locating Changelings would work. The captain agrees, and they begin to search the station crawlspaces again. Then they notice that a display on the central console is counting down: the fusion core is overloading. It is far too late to stop it, so they beam out.
Back on the Lexington, they see a small VinShari skiff approach the station before jumping to warp moments before the station explodes. The saboteur has escaped. Deploying a subspace buoy to restore basic communications between Setu and Narendra Station, Lexington heads to Setu to help with the recovery from the pulsar interference.
A day or so later, the newly-repaired long range sensors pickup VinShari ships entering the outer reaches of Akaru-claimed space. The invading ships soon turn around and head home, possibly because the sensors are now working again. It definitely looks like a raid was planned, but despite Akaru fears, it was probably opportunistic.
The Arc: The VinShari are expanding the range of their depradations, and the Akaru are scared of the possibilities.
Observations: Pulsars are high-density stellar objects that project tight beams of energy from their magnetic poles. They rotate extremely fast, and the beams sweep across a fixed circle of space over a short regular period of time. The energy beams themselves are powerful, but are also accompanied by high energy subspace field distortion “beams” that travel much faster than the speed of light and can overload communications and other systems relying on subspace field dynamics.
The high angular momentum of a pulsar, arising from their density and rotational speed, means that it is virtually impossible for the orientation of the beam to change naturally. Zepht posits that there may be Tilikaal technology able to do this.
References: The subspace relay station is unmanned, but otherwise resembles Relay Station 47, as seen in the Star Trek: The Next Generation episode “Aquiel”. It has no personnel accommodations or shuttlebay, with the habitable portions consisting of a central control room, docking facilities and a number of crawlways.
The Akaru flotilla commanded by Muafo is made up of 6 Iryax-class frigates, a type first seen in “Joy’s Soul Lies in the Doing”.
Questions: What caused the pulsar to shift? Are the VinShari planning to invade Setu, or was this just an opportunistic raid?
