Characters

What happened to all of my characters I log back in to Pandaria and only 1 server and all of my toons are gone.

What happened?

Depends on when you logged in last time. Back in January there was a moltdown, database stolen, all chars lost. Afterwards were two realms - Frostwolf and Sargeras, but Sargeras died out, so they got united under name of Frostwolf. Not sure if Sargeras is still available in realmlist or if these chars are lost.
