Character recovery

Hello, so for some time i wasnt playing wow, i was busy with some stuff and now when i came back, i saw that there is only frostwolf on pandaria realm list, and my caracters are gone from the other realm, is there any way i can retireve them to frostwolf?

You were able to transfer your chars to Frostwolf, but not anymore. So your chars might be gone completley unless the gms can get them back to you somehow.
