Star Trek: Away Missions Romulan - Sela’s Infiltrators Expansion

The Romulans are always after more Intel on their foes, learning their strengths and weaknesses and how to defeat them.
While doing so they will be running plots within plots, planning assassinations and devious stratagems to derail their opponent’s plans.

Romulans avoid conflict until they have a decisive advantage, then make a well-directed surgical strike.
