Unfortunately, I don't think we can read much into this. I still had my co-leader alt in NEW until a few months back and I would see that she had logged in every now and then, but I have not had contact with her for a couple of years. On the plus side, she still refreshes her castles and her keep, but I presume she is just too busy caring for her parents to be able to devote any serious time to Sosaria.
