Dash is first to leaveIt's an almost surreally Ronnie-esque experience. I mean, I still remember what both of those stories were going to be about, but man am I bad at being coherent for myself.

Zero-ish spoiler summary: In Equestria's future, Twilight has cured death--even for those who would wish otherwise.
A few thoughts: This story suffers somewhat from a lack of explanation: it asks the reader to buy this particular vision of Twilight as a well-intentioned tyrant with only a passing "she felt bad when her friends died, and doesn't want that for anyone else," it asks us to believe that Discord is an active participant in this world with no explanation at all, and so on. These sorts of things aren't irreconcilable with the characters, but they're pretty significant leaps to ask the reader to make unassisted. Beyond that, it ends on a very unresolved note--Discord's "solution" doesn't seem like it would be satisfying to Twilight or Care Free, in more of a "worst of both worlds" than "reasonable compromise" sort of way--and ultimately isn't much more than a glimpse at a pretty standard "enforced happiness"-type dystopia. Still, those those kinds of dystopias are popular for a reason, and the writing quality here is well above average.
Recommendation: Whether you're enjoy this story or not probably depends on how far the premise will carry you. If a brief exploration of somepony wanting to die, but being prevented from doing so, sounds inherently interesting to you, this is likely to prove a good choice. If that sounds more like a jumping-off point than a raison d'etre, though, this might leave you wanting.

Zero-ish spoiler summary: Twilight recounts Cadence's descent into darkness and subsequent banishment.
A few thoughts: This story is at its best when, as the title and description do, it directly connects Cadence and Twilight to Celestia and Luna's earlier, corollary struggle. The writing is telly by design, but I nevertheless found this wasn't a choice I appreciated. Twilight doesn't appear to be "telling" this to anyone (or writing/recording it) in-universe, and the style doesn't support that interpretation anyway, which left me feeling acutely aware of the non-meta medium (i.e. I had trouble with immersion). It's probably also worth noting that the season 6 premier trashed this story's ability to fit into canon pretty thoroughly, despite the fact that this was published the day after the S6 premier. Presumably this is the source of the AU tag, though it seems like it would be easy enough to alter the story to fit canon without making any major changes to the tone or other events of the fic.
Recommendation: A lot of the reason this story didn't grab me came down to the style, honestly. If you enjoy first-person recollections which aren't grounded as in-universe stories, memoirs, or the like, this does make for an interesting alternate future.
