The First Seeker is the elected leader of the Starfinder Society. The position has a short term. The Second Seekers faction directly serves to further the First Seeker's goals, and as such its membership and priorities change along with the First Seeker.
The current First Seeker is Ehu Hadif. His goals as First Seeker focus on a "back to basics" approach favoring exploration and research.
The previous First Seeker was Luwazi Elsebo, who led the Society following the Scoured Stars Incident and stepped down after the Year of a Thousand Bites.
Prior to her, the First Seeker was Jadnura, who was lost during the Scoured Stars incident.
