I want to know if it is possible to retrieve one of my first characters, I was playing on this server a very long time ago, and I lost most of my characters since a few changes occuried and I wasn't playing at that period.
I found screenshots of my lvl 80 character named "Moelle", it was an Undead DK, on "Ragnaros PVP" realm, I don't know what happened to Ragnaros, I don't even remember if it was already Warmane at that time, but if a merge occuried, is it possible to find him on a data base ?
do you remember that around january-2015 all molten players have lost their chaarcters and they all had to start from 0 ?
If you have played even after that event, theoretically your "Ragnaros" character have been moved to Icecrown realm
Basically "Ragnaros" and "Deathwing" got merged into "Icecrown" realm: http://forum.warmane.com/showthread.php?t=327761
