Twilight Sparkle's curiosity could be her undoing. For many months she has been obsessed with studying an obscure and understudied field of spellcraft: Rift Magic. In all that time, she didn’t leave her home even once for anything or anyone. Her sole purpose became to master the intricate and complex spellwork behind her new obsession. At first, her friends, being concerned for her wellbeing, attempted to get her away from of her studies but were shut out by Twilight time and time again. Over time their visits became less and less frequent—except for Rainbow Dash, who took it upon herself to make sure, at the very least, Twilight got enough sustenance. Or perhaps more than enough: since, as Rainbow soon found out, Twilight would absentmindedly consume anything and everything that Rainbow set before her. Naturally, excessive eating and a complete lack of exercise affected Twilight’s figure. Every pound of fat she packed on made Rainbow more intrigued and aroused than she would admit to anypony. She developed her own obsession, gradually increasing the amount and calorie count of the food she provided Twilight with. This continued until one climactic day, Twilight was ready. She opened a rift to another land, but despite all her preparation and careful calculations, she failed to make the rift stable. In the process of collapsing, the rift sucked both Twilight Sparkle and Rainbow Dash in, then closed behind them.

Now, the overweight Twilight Sparkle and Rainbow Dash are lost in a completely foreign land. They don’t know how to get home, or if it’s even possible. Fortunately, they find a source of food quickly enough, so they’re in no danger of starving. Quite the opposite, in fact...

At its core, this is a fat fetish clopfic containing excessive overeating resulting in weight gain. It also contains inebriation, sexual behavior, and subtle mind control.

This story takes place in a divergent timeline before the events of “Magical Mystery Cure”.
