Wentar does want to build bridges with the Council but we can't ignore what is going on here. Thea asked us to help her and risked her life to save us. To give her the old 'sorry, not our problem' deal seems a little iffy.
In any case, Aquila is clearly affected by the dark side and is very powerful. How long until she decides ruling this planet alone isn't enough and starts poking around other systems?
