Answer: PAJAMAS
Problem: Arbor Day Town/​Bloomsday Town

The image tiles that are part of the puzzle can be arranged into fourteen larger images. Each composite image contains a single sentence from an official translation of a book in the Harry Potter series. There are two examples in each of seven languages. The goal is to identify what chapter the sentence comes from, and which sentence from the translation’s chapter (there may not be a 1-to-1 mapping in the American version) is pictured. To help identify the source of the phrase, the order of the books is the same as the alphabetical ordering of the source’s language.

Solvers should use the sentence number as an index into the name of the chapter (US Version — as hinted by the “no philosophers allowed” in the flavortext). Ordering the extracted letters by the order in which the chapter appears in the books spells out the phrase GHOUL SLEEPWEAR. Looking at the chapter names in the Harry Potter series reveals that chapter six of Harry Potter and the Deathly Hallows (the US version) is named “The Ghoul in Pajamas.” This gives the solution: PAJAMAS.

1. The Russian used here is from the Machaon edition (translated by Maria Spivek) of Harry Potter and the Half Blood Prince, which, since 2014, is the officially published version.

2. The English language editions have this as clause in a larger sentence. However in the Swedish edition, it is its own sentence.
