Yes. The damage is all caused by the link to the Boundary. It's not easily severed, unfortunately.

[And unless the Malnosso feel like taking away that link again as a death penalty, she's not sure of any real way to cut it off for good.]

The difficult part is finding a way to sever the link. After that, it's just a question of trying to repair the damage done. It's been over three years, though, and I haven't found a way to escape the source quite yet.
