Lucky Meets the Gilded Maiden by @Kallper

"The moment he handed her that letter, Lucky knew there was something off about that lady. She had this look on her face like she knew something about him, he just didn't know what, and that made him very uneasy...

It didn't help his nervous disposition that he was so far from home during his visit to the Gilded City. When his nerves inevitably get the better of him, he accidently defaces a monument to her late father and stumbles upon evidence of her plot to betray the treaty with the Lucky's home of the Green Kingdom, the Gilded Maiden's false suspicions that he may be a spy are all but confirmed, leading to a furious reaction.

Lucky's walk home was going to be more terrifying and excruciating than he could have ever imagined"
