I was thinking, since the continents of Azeroth were once all conjoined and the night elf kingdoms were very widespread, what if a group of night elves carried off when what is now known as Northrend broke off and evolved into some weird arctic elf or something like that? I mean tauren and by lore night elves were more widespread than tauren were. So could there be ice elves or Pandaria elves?
Just a nice conversation and maybe some food for thought.
