Spike does his best to fulfill the wishes of his herd, knowing their lives will be much shorter than his. But while Rarity is perfectly content just to be with him, Applejack wishes to bear his offspring, while Twilight Sparkle wonders if there's a way to extend her life? After all, hasn't she been tasked with looking after Equestria?

And what will happen when Trixie and Starlight Glimmer stumble upon their herd?

Note: This series ignores certain events (Such as the Kirin episode as I hadn't seen it nor knew what it entailed at the time) and goes with what Meghan McCarthy implied about Twilight not being immortal.
