The Assessor Gambit

A Living Campaign Mission for 2371

From the introduction:

In this adventure, the Players Characters join in a scientific and strategic meeting held aboard Narendra Station. At this briefing, they begin to see the bigger picture of the strange goings-on within the Expanse and how alien technology and artifacts are related to the revelation of something called the Tilikaal. The Players will investigate the disappearance of Federation sensor probes, and then run afoul of a Romulan landing party on a massive Class-M world teeming with ancient power. The Players will have the opportunity to encounter a new alien character, who is as mysterious as anything else they’ve yet encountered.
