Caledon Forest is the first region you enter with a sylvari character. I never paid too much attention to it other than realizing that the sylvari get in touch with risen pretty fast. When I went through this region again to get all the screenshots, I found an asura who told me about the Soundless. They’re kind of in between the sylvari and the nightmare court. I am curious about this aspect: Why do sylvari cut off from the Dream? To me, it sounds pretty practical to have such a connection. ;)
At least, the Soundless aren’t torturing and killing everybody who doesn’t want to follow them. They seem pretty peaceful.
