I’m still of the belief that Avaloren = Avalon, so WoW’s version of Camelot. It’ll be classic, traditional western fantasy if that’s the case. No new OC’s but a lot of established WoW races that will fit the mold. The Arathi capital being similar to Camelot, dragons, ogres, gnolls, witches in the form of the Drust returning with a new coven, feral worgen, giants etc. Quite possible there’s new Titan Keepers there too in the form of Merlin and Morgen Le Fay but I could also see them as Life themed if Nymue from Amirdrassil is anything to go by.
