Also, traumatized young Chandra may not have grown into the most reliable narrator later in life. I mean, some things are clearly off, like her missing brother, but she may have made other parts up as a coping mechanism and it's not like Gideon would have had the correct info to call her on it.
Or maybe Gideon had enough skeletons in his cupboard himself to not call other people out on their retconned origin stories...
The worldbuilding was barely there though. It's not like there was an abundance of details there.
Yes, the details don't match up very well, but let's not blow it out of proportion either.
It's not like the worlds we saw would have been terribly interesting to start with.
I'm not trying to blow things out of proportion, and it's not three sentences in a book being contradicted alone that makes me angry, I'm just saying the next block won't take us into retcon-free territory either, both in terms of worldbuilding and actual Chandra-related story details. For instance, based on what we saw in
Magic Origins, I'm almost prepared to bet that Chandra's very dead conservative peasant mum from TPF will turn into a not-so-dead aether smuggling rebel mum and step out of the shadows to lead the eponymous
Aether Revolt in the upcoming block. Or something equivalent to that. And it's not like the glimpse of Chandra's homeplane in the novel was weirdly specific and hard to integrate into a particular setting. The fact that it isn't a previously established plane we've seen on cards before is exactly the point; if Creative couldn't even work with that tiny shred of info without retconning it, then they just did a really bad job there. Nowhere in TPF does it say Chandra's homeplane can't be Clockpunk India, so taking what little info there was and building a cool plane around it would have been perfectly possible. Since the second set of
Kaladesh block is going to be about a revolt anyway, I don't get why they couldn't at least keep the foreign invaders in there and have the conflict be about their occupation. And let's face it, taking exactly the aspects from the novels they were going to retcon (aka the Origin Five's origin stories) and shining a huuuge spotlight on those retcons by dedicating an entire core set (aka
Magic Origins) to them wasn't exactly the smartest move if they want storyline savvy people to not be angry.
It is really exactly as Raven says. It's not just about some stuff about Chandra's homeplane, it's about the entirety of
Magic Origins plus what they did with Tarkir block plus the myriad of smaller Eldrazi arc related retcons plus the generally unsatisfying story of BFZ and OGW, and all of that
in a row. That stuff really ate up most of my good will. I've been playing Magic for about 13-15 years now, I've been following the storyline for almost as long, and it was the Vorthos aspect of the game that caught my attention in the first place. In all those years, the trias of Tarkir-Origins-BFZ was the
first time ever that being a Vorthos and storyline fan genuinely diminished my enjoyment of the game instead of enhancing it. I just can't identify with what they're doing anymore. Sure, SOI is absolutely amazing in so many mind blowing ways, but apparently everything's going to be back in disappointment mode after that.
As to Ravnica and Mirrodin, well. I see the return of the Guilds more as a somewhat inelegant in-universe change rather than a retcon, and I can see why they weren't going to do Return to Ravnica without the Guilds. It just isn't anywhere on the same level as the pointless and unwarranted retcons in
Magic Origins. Mirrodin being repopulated might be one hell of a retcon, but - and I remember us having had that discussion before - it's just more in line with what I expected the ending of
Fifth Dawn to be like. Everyone vanishing because of the soultraps being destroyed never made sense to me in the first place, and
Scars of Mirrodin fixed the exact thing that always confused me. Besides, with all the issues Mirrodin has always had in terms of timeline, worldbuilding, story-card-integration etc. I don't really hold it to very high standards storywise.
