On Reddit has been published an interesting message related to one of the most prominent video games in the Nintendo Switch and Wii U catalogue. In this case we are talking about Zelda: Breath of the Wild.
The post below shows us a detail that you may have missed in the game: only Rotver and Prunia in the Royal Ancestral Technology Lab seem to use what resembles real-world pencils, while the rest of the characters in the game write using pen and ink. This shows that the researchers have a more advanced knowledge, the proof of this being the fact that they use more complex and modernised writing instruments.
You can see for yourself here:
TIL the two tech labs (Akkala and Hateno) are the only places with pencils instead of quills from Breath_of_the_Wild
