But why should it? If you are completely ignorant of any supposed "truth", then there's no reason to be upset.
I mean, let me ask you this: Right now are you, Chaosmancer, feeling at all put out or ignorant about living on Earth right now? Are you perpetually po'd? Because there's a pretty good chance that there's an actual multiverse out there, and thus your objective "truth" right now on Earth is false. Someone else out there in the multiversal cosmos is laughing at you for not knowing what's "really going on". Does that bother you? I mean, by the way you and a few others are talking about the D&D multiverse thing, you should be bothered. Even though you have nothing to base your anger on.
However, I'm willing to guess that you probably aren't. For a couple reasons. 1) You have no idea if in fact there *is* a multiverse or if there *are* people out there laughing at you. For all we know, it's a bunch of BS. And 2) Even if there is, you're never going to experience it or see those people involved, so from our perspective whether or not it exists is completely inconsequential. One of our quantum physicists can claim "Oh yeah, it's all true!" all they want... but if we're NEVER going to experience it... it doesn't matter.
And the same holds true for anyone playing Eberron. Eberron is a closed system. Even if there *is* a "greater truth" out there... as far as the people of Eberron are concerned... it's existence is probably total BS, and even if by some whackadoo philosopher's beliefs it *is* true... no one in Eberron is ever to know it for themselves anyway. So the "truth" doesn't matter. And that's exactly why what Crawford and Company say ALSO doesn't matter.
If we live in the Matrix, but we never know that we live in the Matrix... then do we?
But you are equating real life with fictional investment.
When you write a story, or portray a story, or set up a fictional universe, you set expectations for the people who will be experiencing it. This is why the escalating threat and power-up cycle of Shonen anime becomes a problem for those shows. "Here is the greatest threat to walk this planet, we cannot defeat it, we train, we defeat it. Now here comes an even greater threat far beyond that of the previous threat, we cannot defeat it, we train, we defeat it. But it was no where near as dangerous as this new threat, we cannot possibly defeat it, we train, we defeat it." At a certain point, it just becomes ridiculous, and part of that is you have to eventually break the previous scale to make things fit.
So, no, I personally don't feel stupid because some 7th dimensional being is doing the equivalent of laughing at me, nor do I expect the Sage of Blackmoor to feel stupid because some higher plane spelljammer captain is laughing at him. I do get upset when I get the narrative of "The Sage of Blackmoor is the wisest and most well-read sage amongst the planes, and has walked many of the different planes, mapping them for adventurers who will come." and that is followed by "People of Blackmoor have no idea the true shape of reality, the ignorant people still believe their maps are accurate while spelljammer captains know there is far more to the multiverse than they could ever imagine."
The Sage has now gone from an immense figure amongst the planes, to a footnote amongst the "true planes". And that is what gets people upset, the changing of the narratives because we are beings who can see the DnD multiverse layed out, and we have investments in the stories of some of those setting we are now being told are completely wrong.
If your homebrew is so boring that your players want to find a way to go to Eberron instead, the problem isn't with Crawford...
I'm sure this was meant as sarcasm, but... isn't the entire point of connecting these places so you can travel between them?
Why then is Krynn so boring that your players want to go to Faerun? Or Vice Versa? Or head to Mystara from Dark Sun, or ect ect ect.
Which brings me to a more serious point, and my initial point, is it really necessary to connect these places when a seemingly massive amount of the player base has no problem running their games in only one setting and little desire to run it in multiple settings, if these connections are never being referenced, they do not need to exist. Whether or not they have existed in the past is immaterial.
But if any of you keep posting your annoyance at the whole D&D multiverse thing and continue to say "Wizards of the Coast shouldn't be saying that!", I'll keep showing up to say quite succinctly "You're too late, they already have said it. So now what are you going to do about it?"
But a multiverse itself does not lead to these problems.
It is when a multiverse setting says "people believe these truths about how other planes exist (and those are absolutely true within that setting, so that the way the planes interact with each other in Faerun is completely true) but they are completely wrong unless they agree with how this setting shows them, because this is the setting of showing us the entirety of the multiverse, not just a piece of it"
That is not necessary to a multiverse, a multiverse can exist without travel between it's various realities even being possible. So, in fact, the genie is not out of the bottle, until they sit down and tell us that despite having these planar cosmologies for the settings like Eberron and FR and Mystara being entirely seperate, they are in fact all the exact same and look like this.
