Blizzard has added two new Europe Realms for those who wish to start anew with level 1 characters. For now there won’t be migration services to these two realms. Expect more realms after Wrath of the Lich King.
Realm names: Azuremyst and Terokkar
Realm type: Normal (PvE)
In more words
Today we’re opening two new English Normal/PvE realms, named Azuremyst and Terokkar, in the Ruin Battlegroup. These are fresh realms, thus no migration will be allowed to the realms during the first months.
The realms will open this afternoon/evening.
Please note that the starting areas may be quite flooded in the beginning, and the population cap is intentionally set a bit lower than normal to not have them even more flooded. The cap will be raised over the coming days as the population spreads out more.
Update 17:30 CEST: realms are now live. Enjoy!—source
