The Seeker is a Career from the Force and Destiny Core Rulebook.
It is not uncommon for some Force adepts to feel compelled to travel throughout the galaxy to aid those in need and to oppose those who use the dark side. While some might focus their attention in cities and urban centers, the need can be just as great far from the heart of galactic civilization. A Force adept who is willing and able to travel and work in these environments can help ease crushing poverty or crippling plagues of hunger and disease. They can also discover new Force techniques, find themselves in need of training, and at times halt dangerous threats that could otherwise fester in isolation. A Seeker must be capable of doing all of these things, while traveling far from any meaningful support network.
Qui-Gon Jinn is an example of a seeker in Star Wars.
