Lyra was never supposed to have a cutie mark for weather-work. She's a unicorn! She's also pretty bad at weather spells. Just as she's on the verge of giving up and studying, Twilight comes up with an alternate plan.

And now there's dragons. A whole world full of weird little fleshy non-fire-breathing dragons.

This is vaguely inspired by 'Twilight's World', in that it's using what I thought was the premise of that story but turned out not to be the case.

It's a crossover with Pheobe and her Unicorn, X-Com: Enemy Unknown, and Fallout 4.
