Orcs are extraterrestrial beings. As are Draenei.
The literal first expansion of this game was a medieval/sci-fi space adventure.
And then you have the Titans, which are literal space gods, being behind most of the origin story of WoW.
People who dislike cosmic stuff have tricked themselves into playing WoW without realizing most lore threads of this game universe lead into the cosmic, one way or another.
This was never “just a place with castles and magic”, when Draenor always existed.
If you thought it was, you never paid attention lol.
