Captain's Log, Stardate 58163.7
We have received disturbing news from Cestus III. It appears that two artifacts belonging to the Gorn are missing, and they blame the Federation. If the artifacts are not returned within ninety-one hours, they will declare war. The Melbourne is en route there in order to investigate the theft and recover the artifacts.
Following the orders received from Admiral McCabe, the USS Melbourne arrives at Cestus III. With little initial information, Capt. Mitchell and the rest of the command crew beam down to the Institute for Federation-Gorn Relations. They are met by T'rea, the senior Federation diplomat at the Institute, who briefs them on some of the details. A joint archaeological dig involving the Federation and the Gorn has been operating on one of the northern continents for over a year, since an ancient Gorn site was stumbled upon by a mining operation. The dig recently uncovered two artifacts related to a powerful ancient Gorn leader, known as the Tooth and Claw of S'surest. These artifacts have now disappeared, and the Gorn are blaming the Federation, threatening to declare war if they are not recovered.
Capt. Mitchell is ready to begin the investigation, and as a preliminary step asks Lt. Cmdr. Ahn'Kress to get the Melbourne to request information on recent ship traffic on and off Cestus III from the local authorities. Cmdr. Partav suggests they invite the Gorn to cooperate in their investigation, and Mitchell agrees. T'rea says she can introduce the Starfleet officers to the Gorn delegation at the Institute, where they can make the request. The Vulcan escorts them to the main building of the Institute, which sits between the Federation and Gorn compounds. Inside, they are met by the head of the Gorn delegation, a Russth Gorn named S'ruxin, and two of his aides. Mitchell explains their mission, to investigate and ensure the return of the artifacts, and asks if S'ruxin would like to send representatives to participate. S'ruxin agrees with the proposal, and assigns his two aides, Slas'sar and Griss'lass (both Ruusth-Ssessekh hybrids), to accompany the Starfleet officers.
Due to the time crunch, Mitchell requests to use the Federation compound's transporter to beam them over to the archaeological site, where the artifacts were being kept when they disappeared. Using the compound's transporters as the starting point allows the Melbourne to perform the site-to-site transport with little difficulty, and the Starfleet officers and the two Gorn aides soon materialize halfway across the planet on the outskirts of the dig site. They are greeted by the head of the Federation archaeologists, a former Starfleet officer named Jack Briggan who is now part of the Independent Archaeologists Guild. Jack welcomes them and says he was the one who contacted Admiral McCabe, his former commanding officer, to assign a Starfleet vessel to the investigation when he realized the severity of the situation.
As they head into the site itself, Briggan points out they have kept the Federation and Gorn teams separate since the theft, but the work on the site still continues. Partav wants to search the quarters of everyone at the site, but this will require careful coordination with the Gorn authorities to avoid escalating matters. In the meantime they are shown the crime scene, a lab building with secure storage requiring people to enter their personal access codes to get into the storage. Lt. Stuart starts going through the dig records to get details on the artifacts while Lt. Cmdr. Tir and Lt. Cmdr. Ahn'Kress examine the storage area the items were taken from.
Loto learns that the Tooth and Claw are actually a pair of bladed weapons purported to have belonged to S'surest, an ancient Gorn leader. S'surest was the leader who first unified the different Gorn peoples under a single rule, his, and set them on a path out to the stars. The Tooth is a large saw-toothed sword while the Claw is a multi-edged combination of a throwing dagger and axe which is roughly shaped like a grasping claw. Both remain significant to the Gorn today, with the Tooth forming part of the symbol of the Gorn military and the Claw being the emblem of the Gorn Alliance, the collection of royal bloodlines from which the supreme leader of the Gorn is usually chosen (and many of whose members claim descent from S'surest himself).
The findings arouse Capt. Mitchell's interest and he joins Loto in reviewing the information while the others continue the criminal investigation. The site being excavated appears to be a temple, complete with a sacrificial altar. The archaeologists believe that it was home to a sect that worshipped a deified S'surest. Elevating leaders to godhood after death is not an acceptable practice to most Gorn, as it by definition would make any successive leader weaker than the previous, deified one. As a culture that values strength, and rule by the strongest, this idea is counter to the mainstream belief. Any sect that deified a deceased leader would be persecuted, so this group likely fled the core Gorn worlds to escape this, bringing the Tooth and Claw with them. So far there is no evidence for what happened to the sect, and why they might have left the Tooth and Claw behind, but the work is continuing so such answers may be uncovered in the future.
Mera and Ahn'Kress complete their examination of the crime scene and have discovered that the control pad granting access to the storage area had been tampered with. All evidence points to the pad being bypassed, likely with a tool known to be used by Orion pirates. Such devices are available on the black market, so while someone needs to know what they are doing to use one it does not mean the thief was necessarily an Orion or even affiliated with the Orion Syndicate. The timing points to the bypass being done about a day and half ago, giving a more precise time for the theft.
By this point the USS Melbourne has received the list of ship departures from Cestus III's space traffic control. Based on the presumed timing of the theft, this narrows down the list of possibilities and Lt. Cmdr. Tir starts reviewing the crew manifests of each ship to see if anything suggests a suspect. One vessel does get her attention, a freighter called the Lady Luck whose owner, a human named Arlo Beddo, turns out to be the great-great-grandnephew of Commodore Howard Travers, the commander of the original Cestus III colony who was killed by the Gorn along with everyone else in the colony in 2267. A long time to hold a grudge, but it definitely puts Arlo on the list of potential suspects.
Mera digs further into Arlo Beddo and the Lady Luck, requisitioning subspace communications traffic logs. She finds evidence of a string of messages in recent days between Arlo and a group of other people. These are message addresses Arlo seems to be in contact with semi-regularly, but the activity shows an unusual spike over the last week. Investigation into these others finds similar family connections to the Cestus III massacre, as well as to victims of earlier attacks that would later be attributed to the Gorn, like the loss of the SS Puget Sound. Taken all together, it appears that Arlo is part of a group of people related to victims of attacks by the Gorn, definitely the kind of people who might chafe at a possible lasting peace if they were more revenge minded.
Meanwhile, Loto performs a detailed scan of the interior of the storage area with the help of Ahn'Kress. They are able to find DNA traces in the room that have an 85% probability of belonging to someone related to Commodore Travers, whose own DNA is in their databanks thanks to him having been a Starfleet officer. Loto also detects the residue of a portable emergency transporter, the sort of thing that might have been used for a quick escape once the artifacts had been obtained. The spaceport where the Lady Luck had landed is well within the range of such a device, and the proximity of her departure to the time of the crime, combined with the other evidence, points to Arlo Beddo as the primary suspect.
Capt. Mitchell has everyone beamed back up to the USS Melbourne, including the two Gorn aides. A check with space traffic control indicates that the Lady Luck had filed a flight plan with a destination of the planet Renavi, about 50 light years from Cestus III. Even with a 40 hour head start, the Lady Luck would not have had time to reach there, so Capt. Mitchell orders a pursuit course laid in and for the helm to engage at Warp 9. At the same time, Mitchell has Ahn'Kress send out inquiries to other ships and outposts to see if anyone has information on the target ship. Luckily the Melbourne does receive a response, from Deep Space 2 where their long range sensors had detected the Lady Luck's transponder. At first glance the trajectory of the signal seems to align with a course towards Renavi, but a closer analysis reveals a small discrepancy. Accounting for this, the crew are able to determine their target's actual course, and it is pointing to the smuggler world of Maltharin just inside the Klingon border.
