The main body of Seeker forces were stationed in the city located deep within Yelico Valley, these Seekers are actually a secretive intelligence organization who have devoted themselves to researching the world. Independent from any major political powers, they keep to themselves, and train heavily in order to survive the harsh environments.
Although their military strength is nowhere near the magnitude of the Empire, the Seekers have perfected their guerrilla fighting tactics and can even defeat armed soldiers with only primitive weapons. For these very reasons, the Empire considers them a threat.
