Having much of the story take place outside of the republic's "sphere of influence" would help that to a certain extent, I think there would be more mystery if you were to start without a council, or even a Trask character to help you out.
Maybe you wake up in the woods next to a crashed ship, and after walking around and killing some cranky forest critters you start traveling through the woods and meet someone who can sell you a map to several nearby towns.
Not neccessarily a story suggestion, just a vague example of how to not get dragged through an endar spire
