I kina approve of this message. It is best to move away from the idea of canon. I really like that current practise is to present lore from a view point of some in universe character. That creates the idea of ambiguity and bias in the lore. Which is good and gives DMS more room to breath and not feel the weight of canon.The thing is a rpg has to use the marvel/dc setting idea that the published game is earth prime or earth 616. Your home game is earth 31843 or Oerth 573783. And some people get their panties in a bunch because the eberron or Oerth they are playing in is being run by a DM that deviates or ignores some canon. God forbid he create his own subclass. Who does he think he is. Matt Mercer. You better have a certification to do that.
In my games, lore does not exist until and unless you have interreacted with it as a character.
