While there are several factions to join inStarfield, one of the earliest ones is the UC Vanguard. This offers the benefits of camaraderie, new quests, potential citizenship, and other rewards. However, after joining the UC Vanguard, you met Hadrian and uncovered a terrifying sample on your mission.

Continuing to learn more about the sample is your goal, and to do that, you’ll need to find Dr. Percival Walker. The problem is that he’s not exactly available, and finding another specialist is out of the question. You’ll have to find a way to reach him to learn more about the Terrormorph sample.
