There are better ways of advocating freedom than saying 'do this or I will do that'. Using threats to get your way isn't actually helpful. The better way of t is having faith in what we both know Dorian can accomplish and offering aid to those elves who when leaving slavery don't really know which way to turn. Dorian's idea of offering payment isn't a bad one, and yes there will be those who have taken advantage but that's why you keep pushing. And not threatening.
And there's not only your people there. If you want to help, don't limit it to those only of your choosing.
