How about:
We see Fiera pull out of Dark Hunter training, then The Shadow One sends five hunters out to silence her as she now knows far too much about the organization to be allowed to return to civilization. The Dark Hunters corner Fiera in a jungle on the Southern continent where she stumbles across Kemaru who leads her to the treetop settlement of _______ (can't think of a name) where Fiera encounters Loran who is hired to make their getwaway, with Kemaru coming too because he sees profit in crafting the two weapons, despite his distaste for Loran, a Toa.
Of course we'll have showdowns with the DHs during the escape.
