Your goal is noble, but can easily lead you to dangerous propositions. There is a secret way into the city of Traensyr, one that I would be willing to show to a force powerful enough to traverse it.
Thusly, you can learn more of this wicked city which all too greedily clings to those souls entrapped therein. I would be willing to help you find this route, and from there explain to you the nature and way in which to free slaves from captivity by using methods that the Seekers once shied from.
Contact me if you would truly free those entrapped, now is the time as Traensyr and Ysinode both are weaker than they have been in two hundred years. Indeed, massive slave raids against both city's would perhaps be enough to bring the downfall of each and herald in a new age of prosperity for Dunwarren.
