The Seeker

Full Name: Wanderer's seeker either doesn't have a name and only goes by "Seeker," or has a name, but we never learn it

Past Planets: None; Earth is her first home

Human Host: Lacey

Calling: Seeker

Role in Invasion: As per her job description, the Seeker hunts down wild humans for insertion.

Miscellaneous Information: This young soul occupied the body of Lacey. Earth was her first world, and Lacey stayed very much alive in the Seeker's head, much like Melanie did. The Seeker kept this a secret, and this similarity was the motivating reason that she pursued Wanderer and Melanie with such vigor.
