Main Duties
The principal duties of The Heart hunter's are to keep the peace in the twin settlements and ensure the will of both settlement leaders is followed. If there are any troublemakers in the settlements, it's their responsibility to put an end to the conflict and, if necessary, to bring those who broke the peace in front of their leader for judgment. As with everything else in these settlements, the current conflict with Entrelai is bringing changes to their responsibilities.
I like how you describe the way the changing environment has affected them.
