For a while, Eisen kept staring at the inscriptions on the box, trying to figure out if there was any actual language involved in this. During his days of travel, he learned many different languages to very different extents depending on how long he stayed in the corresponding region.
For example, he was almost fully fluent in German, French, Swedish, Spanish, also Japanese, and English of course. Since he had spent at the very least a year in each of those regions and was able to at the very least handle himself in most other languages so that he would be able to ask the way to a restaurant, hotel, or the nearest train station. Although that was really the most of what he knew in the majority of languages he knew about, and they were just phrases that he picked up here and there, so he should be able to at the very least recognize it if these were based on real languages.
