Rumour has it that Vornskr may be transferring to either The Harbinger or Drooga's Pleasure Barge... so to check if your names have been taken on those servers, all you need to do is try to start a toon on that server, get to the character creation bit, input your name and select NEXT and see if it's available. If it isn't then you're screwed pretty much.
The way it works is that if you have a toon on a PvE West server, it will need to go to another PvE West server, so you can't skip your toon from a PvP or RP server to PvE or anything like that.
The transfer is for individual toons, so you'll have to list which of your toons you want to transfer. When you transfer your toons will be renamed to a random set of letters and the game will prompt you to rename them when you try to log in to them on the new server. Of course, you also have to remember that when you log in you will also have to re-input your LEGACY name which may also be taken.
As of this post, we haven't heard anything more regarding Vornskr, stay tuned and we'll update you though.
