Lindsy had been back from the docking ring for three hours when she finally felt like she had enough to work with.

She had gone straight to the astrometrics alcove when she came aboard, dropped her jacket over the back of the chair, and started pulling data before she had even properly sat down. The four tokens were laid out on the secondary display in order of reference number, each one a set of coordinates with a logged sensor reading attached and nothing else. No context, no vessel identification beyond a scrambled registry string, no explanation of what the logging ship had detected or why it had decided to keep moving. Just the numbers and whatever the numbers pointed to.

Three of them she worked through in the first hour. One was a gravitational anomaly consistent with a collapsed stellar remnant that would be scientifically interesting to someone and operationally useless to the Dutchman. One pointed to a region of dense particulate matter that had probably been a debris field long enough that whatever caused it was no longer identifiable. The third was genuinely promising salvage but nothing that matched the particular quality the Yridian had described when he talked about token three.

Token three was the one she kept coming back to.

She pulled up the raw sensor reading from the token and ran it through her analysis tools for the third time, looking at it from different angles the way she looked at problems that had not resolved themselves yet. The reading was not consistent with any natural phenomenon she could identify and it was not consistent with any standard vessel configuration in her database either. There was a regularity to the energy signature that natural things did not have, a pattern that repeated at intervals precise enough to suggest it was not random and large enough in scale to rule out anything small.

She set the token reading aside and started on the surrounding data instead.

The coordinates the token carried were precise but coordinates without context were just numbers. What she needed was everything that surrounded those numbers, the navigational history of that region, the traffic patterns, the chart gaps, anything that would tell her what kind of space she was looking at and what had been happening in it.

She pulled every map she had for the outer sectors, current Federation charts, two older Bajoran surveys, and three legacy corridor maps from her personal archive that predated most of the political boundary shifts in this part of the quadrant. She layered them on top of each other on the main display and looked at where they agreed and where they did not.

The gaps appeared almost immediately.

Not navigation hazard gaps, not uncharted regions, but absences in the data that should not have been there, smooth blank spaces in the middle of areas that were otherwise reasonably well documented. She had seen that kind of gap before and she knew what it usually meant. Someone had made a deliberate decision not to include something when the charts were compiled. The gaps were not natural and they were not random and they clustered in a pattern that was too consistent to dismiss.

She cross referenced the gap locations against the token coordinates and then against the Borg sensor specifications from the ship's equipment manifest.

She stopped.

The Borg derived sensors the ship was carrying had a frequency range that overlapped almost exactly with the interference profile of the Lantar Nebula which sat between New Ferenginar and the outer sectors the token pointed toward. She had noted that days ago as an interesting navigational detail and filed it. Now she pulled it back out and looked at it alongside the chart gaps and the token reading and the pattern that was assembling itself in front of her started to have a shape she recognized even if she was not ready to name it yet.

She started triangulating.

If a vessel had been moving through the outer sectors on a heading consistent with the scrambled registry string attached to the token, and if it had encountered something significant enough to change course at maximum warp, the most probable location of that encounter fell within a range she could calculate from the heading data and the timestamp on the logged reading. She ran the calculation three times with slightly different parameters to account for uncertainty in the registry data and all three results came back within a tight enough cluster to be meaningful.

The cluster pointed to a specific system in the outer sectors. Far enough off the established shipping lanes that regular traffic would not pass through it. Far enough from Dominion territory that whatever was there had been sitting undisturbed through the war years. And sitting inside the cluster were three of the chart gaps she had identified, three deliberate absences in the navigational record of a system that someone had decided at some point did not need to be documented carefully.

She sat back and looked at the display for a long moment.

The Gatrao System.

She had legacy data on it. A mining station that had been operational until roughly a decade ago and had gone dark without much explanation in the official record. Traffic in the region had dropped off after that and the charts had been updated less frequently since, the kind of gradual navigational neglect that happened to systems that stopped being commercially relevant.

It was exactly the kind of place something could sit for a long time without anyone looking closely enough to find it.

She pulled up the token reading one more time and looked at the energy signature with the Gatrao System in mind and the regularity of it, the precise repeating intervals, the scale of it, settled into a context that made it considerably more unsettling than it had been when it was just numbers without a location.

She saved everything she had built, the triangulation data, the chart analysis, the sensor cross reference, the route calculations she had started sketching toward Gatrao, and flagged it for Zedd with a message that said she had something worth looking at and that he should come to astrometrics when he had time.

Then she looked at the display for a moment longer and thought about a ship that had changed course and run at maximum warp and filed no report and thought about what kind of thing made a ship do that and whether the Dutchman was actually ready to go find out.

She poured what was left of her afternoon tea, cold by now, and drank it anyway.

Five bars of gold pressed latinum was starting to look like a very reasonable price.
