Let's go!

I imagine I'll do something dragon related, but I am also a big fan of all shades of Warcraft elf and then also Kul Tiras.... decisions decisions.

The removal of the Legion as a unified body brings up the question of if fel magic/demons are still a thing at all? I think cutting them entirely out wouldn't be ideal, I find warcraft demons and fel a pretty fun play on the usual fantasy demons/corruption tropes and it would be a shame to completely remove them. Blood elf vibes for the win.

EDIT:

Collecting my thoughts a bit more on this, I'm not sure why the One Legion thing would mean that the Legion in this timeline would be cut off, as we see in WoD and both Karazhan instances its not that the Legion is only interested in main Azeroth its that they are pan-reality. Until the Legion is defeated on Argus in the main timeline surely they would still be a substantial threat?
