It's nothing big or new but a mob in Dalaran Sewers is named after my vanilla guilds raid leader Amera who played a paladin named Sky in BC. The mob is named Amera Sky and has the same face/hair style as Sky. He was also a gladiator which could explain why she's around the arena people. Our original guild leader turned out to be on some part of the dev team and he added this.
It is posted on the wowhead comments as well but just a neat easter egg I knew about I thought I'd share. These chars are on US - Blackhand
