Let's go with "as far away from Artuur Vahkran and his paranoia as humanly possible" or, about the other side of Avalon from the Imperium. The free cities are kinda in the middleish, with the Imperium to the east, Baldurheim past that, and the Forests of Wrelm wrapping around the south and southwest of the free cities. I can't draw maps to save my life so I didn't.

I wouldn't make it more than two posts. You don't have to arrive in the same post you write, but the journey there can mostly be handwaved over. We'll also do some handwaving to ensure everyone arrives at Silverwick at roughly the same time for convenience.
