No one's characters are going to be forced into mortality against their will.
I know, but I will keep my opinion about the subject.
I love the realm, but it's dead. I had more activity in Vix and I believe the "new" southern realms are enjoying more activity in general. Even war is not solving the problem. Sirion have endless wars, against direct enemies or to help allies. However, the realm is empty of any activity beside orders. When even war cannot solve it, people will just seek another realms waging war where they can feel they can help to improve something. In a small scale, I noticed it in other realms as well, so it's not just a Sirionite problem. If they just begin in Sirion, well, they will not come back.
