Monster Ecologies

Man I love my youtube subscribers and all their excellent comments!
I really do, it is the main reason I started making monster ecology videos, because that was the feedback I got from people.
This morning, I woke up and checked my comments feed, and there was a series of fairly abusive remarks from Alexis The Dragon, which started out kind of constructive, with corrections on how to pronounce Baator and Acheron, and comments about the conflicting tales of the origin of the Nine Hells, the version of the cosmology of the planes.. but, then it sort of went off the rails and ended up being just abusive, saying I was pulling information out of my ass, that I should not be making lore videos if I was not presenting canon information, etc.
Well, comments are a privilege, it is, after all, my channel, and rather than get into a pointless argument with someone who seems to expect me to be something I never claimed to be, that is, an expert on monster lore, I just blocked the comments and publically notified the channel what had happened.

See, I never claimed to be presenting nothing but absolute facts, a lot of what I draw from is wiki articles, blogs and such, also, the subject matter is far more complex than even my lengthy videos can cover.
Alexis pointed out that the Asmodeus lore is conflicting, and said he could not recall the other version.. yeah, which one?
The one where he was the archangel of a god who he killed and the Nine Hells was that former god's domain?
Well that is fine, as long as you ignore the complete rewrite that happened to all of that in the 80's due to religious persecution of the hobby.

Look at a first edition monster and compare it to a fifth edition version.. a lot of changes!
Which one is factually accurate?
Not important, because I am making videos about the current edition of the game, I may reference older information, but I try to stay on track with the current edition and just enrich the current world view.
So with the infernals and demons and fey and divine lore, it is going to be very muddled, but, people want to hear about it, so, I will do my best.

I never claimed to be the best, I have no obligation, my videos are just entertainment, designed to inspire ideas and allow DM's to sit back and think about the creatures, examine all the angles and bring interesting new facets to the game for the players. and themselves, to enjoy.

I am not a monster encyclopedia.
I'll answer questions as best I can, from the resources available to me, that is the best I can offer.
