I'm not certain where you got your information that most players will not continue to develop their characters. I didn't see any poll on that, official or otherwise, and haven't been asked in any other way. I can say absolutely I don't intend to stop developing Jennara. I'm still here for the same thing I was here for two years ago.
In Leanthar's original status of v3 post, it was mentioned that there is a system to reattach broken strands of your soul. What is the prospect of activating that system in the near future?
