I think you have legitimate issues Daimoth, but I think there is merit to the old Mystics. They just keep that stuff secret and in effect it doesnt have a lot of noticeable positives. I honestly think it has a place to exist, and the members in the guild seem very community-based and try to do things that they feel are good for us as a whole. Personally I have a different perspective that I want to get heard, and this provides both an option for mystics who don't see eye to eye with current council policies, but also a means of bringing public attention to the whole thing. Those who disagree with the Shadowguild's ways can join the mystics, and perhaps one day both guilds can work collaboratively on new things to make being out of the library more appealing for all of us.
The anger and rage is more of a plot device, and hopefully will not transfer onto any individual mystics. We really don't want to make enemies, unless those enemies realize they are playing a part for the enjoyment of everyone as per some huge player-run story
Still any legitimate problems with mystics should be heard, and the Shadowguild will listen to those grievances and try to include nonmystics in our plans.
